When the radio is first powered up or after a reset, it will ask you to select
the geographical radio operating region, use the rotary control to choose your
region and press the knob to select. This can also be set using the Radio Mode
menu – all menus are context-sensitive i.e. Radio Only functions can only be
accessed in radio mode.
Button Functions
The function of some controls depends on context. For example, the 1 button is
used to recall (short press)
or store (long press) radio station preset 1, However, when playing media (USB
or BT), pressing this button will toggle play/pause.
Bluetooth Operation
General Operation
When paired to a mobile phone Bluetooth-enabled radio models, allow the user
to perform hands-free calling via the radio. The radio has Answered” and
“Hang-Up” buttons to accept or reject an incoming call.
When no call is active the Answer” button can be used to re-dial the last number – pressing once asks if you want to re-dial, pressing again dials the number, pressing the Hang-Up” button cancels the request.
Bluetooth Profiles
Bluetooth enabled units can wirelessly link to Bluetooth devices such as
mobile phones
The modes of Bluetooth connection are referred to as profiles” Tis radio
supports the following profiles:
1)A2pp ; Advanced Audio Distribution Profile – Playing (Streaming) music
using Bluetooth. Devices that have A2DP functionality can stream music into
the radio to be played through the vehicles loudspeaker system.
2) AVRCP : In addition, if supported by the device, the AVRCP profile
(Remote Control Profile), allowing functions like ‘next track’ and ‘previous
track to be controlled from the radio.
3) HFP ; Handsfree Profile – Making or receiving telephone calls using
Bluetooth.
4) SSP : Secure Simple Pairing – this method is based on a random number
generator and the user does not need to enter g PIN number on the phone
Pairing
To use the Bluetooth hands-free function a mobile phone needs to be paired” to
the radio. To “pair the mobile
phone with the radio ensure that the radio is turned on. On the mobile phone
search for Bluetooth devices and select the supplier’s reference model number
RM1801. Check for a successful pairing notification on the mobile phone.
Once paired it is the mobile phone that determines automatic reconnection to
the radio. (e.g. on re-entry to the vehicle with the ignition on). To
disconnect a Bluetooth device temporarily use the DISCONN” (disconnect) menu
function. To permanently

automatically seek the next available
frequency (ump to the next to seek to stop).
Manual Tuning
Long-press either the >>] or ]<< button to change to manual-seek mode. In this
mode, a short press of one of these seek buttons changes frequency one step at
a time whereas a long press will scroll until the button is
released. The radio will revert to auto-seek mode if either button is not
operated for 3 seconds.
AutoStore Radio Stations
Long press the BAND button will start an “auto store” sequence to scan the
whole band and store the strongest stations found.
Searching for Radio Stations
When listening to a radio station a long press on one of the radio preset
buttons will store it permanently. The current station will be saved. A stored
radio station can be recalled by a short press of one of these buttons. The
stored radio station can be updated by tuning to a different station and
performing a long press.
Long press : Store your favourite radio stations using radio station
presets.
Short press : Recall the stored station.
FM Radio
Radio Data System (RDS) is available in many countries. If an RDS broadcast is
present, RDS functions such as AF and TA can be enabled or disabled. RDS is
only available in the FM bands.
Radio RDS Notes
When RDS (Radio Data System) is operating the radio will show the station name
e.g. “BBC R1” rather than the frequency. RDS is only available on the FM band.
If RDS service is not available, the radio operates in conventional FM radio
mode.
AF
Alternative Frequencies. When this feature is enabled, the radio can stay
tuned to BBC R1 by automatically returning the reception frequency when the
first signal becomes weak such as when the vehicle has moved out of range,
providing that a stronger signal on the alternative frequency is available.
Channel switching to the same radio station is performed automatically. In
infringing the reception areas the user may switch off AF if silent frequency
seek is experienced frequently. Choose the AF menu item and select OFF.
TA
Traffic Announcement. When switched on, if a traffic announcement is available
the radio will automatically switch to the station broadcasting the
announcement until it is complete. The TA menu item toggles between TA ON and
TA OFF.
TP
Traffic Program — An indicator is displayed if the currently tuned station is
a traffic announcement capable station.
PTY
Program type. RDS broadcasting services categorize the type of programs for
the listener. Examples are NEWS, AFFAIRS, INFO, SPORT, EDUCATION, DRAMA,
CULTURE, SCIENCE, POP M, ROCK.
Radio Preset Notes
FM has 3 bands, FM1, FM2, and FM3 bands each band has 6 radio presets. In
total there are 18 FM radio presets for the user to store pre-tuned radio
stations. MW has one band with 6 radio presets, as does LW. There are 12 AM
(MW & LW) radio pre-sets. In total there are 5 x 6 = 30 radio presets. The
radio stores these permanently on an EEPROM memory device, that does not
require external power to retain the radio station preset memory.
Media USB
One single media device can easily fit thousands of songs (audio tracks).
These tracks are often referred to as
MP3 and WMA. Without any specific metadata, the radio uses the track filename
as the title. Tracks can be put into folders and sub-folders.
For media carriers such as US sticks, the unit can play files inside sub-
folders
Avoid having too many levels of depth in the sub-folders.
Do not carry too many audio files on a media to avoid difficulty in finding
the desired song/track.
Media software and hardware are updated at a fast pace, so although the radio
is shipped with the latest media compatibility; newer US8 sticks and/or new
file formats may not be compatible.
Listed below are the alternative functions of various keys on the front panel
for media play-back.
| Next track (short press), Fast forward (press and hold down)
---|---
| Previous Track (short press), rewind (press and hold down)
| Play and Pause playback
Repeat play mode, ppr 1pK repeats the current track when it has reached the
end, pT ELD repeats playing
of all the tracks in the current folder. PT ALL repeats all the tracks in the
entire media library.
INTRO Intro-play INT indicator will be shown on the LCD display. When in this mode the radio will play the first 10 seconds of each track (intro) then skip to the next track. When at the desired track, press the INTO button again to cancel the intro-play and listen to the whole track.
RDM Random-play, RDM ALL randomly plays from all tracks, RDM FLD plays tracks randomly from the current folder. RDM OFF plays tracks in the order they appear in the folder
FLN/FL Previous folder and next folder
There is a BROWSE feature that allows the user to cycle through the available media by folders and files to select a track. Press the BAND button to select this mode. Rotate the volume knob to scroll through the folder/filename/tracklist. Press the volume knob to select
Reset – Software / Hardware
Soft Reset – MENU – RESET: If the user is not sure if settings on the radio
have been altered inadvertently, restoring the factory default settings may
help. On reset factory settings will be reloaded, overwriting the current data
selections with their default values. This includes such items as BT pairing,
station presets tone settings, etc.
Hard Reset – A hardware reset button is located on the front panel (see “Front Panel Layout”) and can be activated by a paper clip or pen. This is only necessary if the radio refuses to react to any button input.
Power Off Timer
This radio has a power-off-timer enhancement feature. The setting for this is
accessed by a long press on the
MENU button (system menu), in any mode, and using the >>I or ]<< buttons to
select the timer menu. Settings are OFF AUTO, 30 min, 60 min, and 90 min. OFF
is the factory default value where the radio powers
off immediately when the ignition key is switched off. This is the same as
conventional radios.
AUTO mode will switch off the radio with the ignition, but you can turn the radio back on (or off) for a 30-minute period.
30, 60, or 90 minutes will keep the radio playing for this time after the ignition is switched off. Turning the radio off manually will cancel the timer and the radio will not switch on until the ignition is also turned on. This countdown timer is shown on the display using the small secondary line of characters. In the last 5minutes of the countdown timer, the main display will warn the user that the radio is about to shut down.
This feature extends listening time and allows the ignition key to be removed for safety reasons. It also prevents the battery from being drained if the radio is left turned on for an extended period. The exact availability of this feature depends on the type of the vehicle since both a switched ignition “ACC” wire and a permanent battery “B+” wire are used to control this function and must be connected to the radio.

Wiring Notes
Connections are to be made at the rear of the unit during installation.
Connector A Pins:
A4 B+ or BATT +12V
When the radio is turned on electrical power is supplied to the internal
electronics of the unit through this pin.
Main consuming blocks such as audio power amplifiers and backlights draw power
from this pin. Ensure the
connecting wire has a minimum AWG14 wire gauge to carry the current.
A5 AUTO ANTENNA OUTPUT +12v
The voltage state on this output pin is a direct indicator of whether this
unit is powered on or off. It can be used to control ancillary equipment such
as an automatic electric antenna or an audio power amplifier. When connected
properly such ancillary equipment will power on and off automatically in sync
with the radio.
A7 ACCESSORY {ACC) or IGNITION +12V (key position)
Normally connects to the ignition or accessory circuit. By sensing the voltage
on this pin, the unit is able to
automatically power on and off when the ignition key switch is turned on or
off.
A8 CHASSIS GROUND {EARTH)
All electrical current from this pin is combined to complete the power supply
circuit. Ensure the connecting wire has a minimum AWG14 wire gauge to carry
the current. The metal enclosure of this unit is grounded to this pin. The
unit is only suitable for “negative earth” vehicles.
PINS A4 and A7 B+ (BATT) and ACC (IGNITION) CAN BE SWAPPED BY CHANGING THE
POSITION OF THE FUSE – (SEE DIAGRAM BELOW)

IMPORTANT NOTE:
Always replace the fuse with the same type and rating.
A blown fuse usually indicates a problem in the circuit.
Do not rely completely on replacing the fuse to fix a problem. An over-rated
fuse will compromise protection
against over-current.
Under-rated fuses can blow even if a fault condition does not exist.
