Global RM1802N Audio Mechless Instructions

Media USB / CD-ROM

One single media can easily fit thousands of songs (audio tracks). These tracks are often referred to as MP3 and WMA. We use (computer) filenames as track titles. Tracks can be put into folders and sub-folders.
For media carriers such as USB 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 desirable song / track.
With media, both the hardware and software get updated at a relatively fast pace. The unit is shipped with the latest media compatibility; newer USB sticks and/or new file formats may not be compatible with this unit.
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. RPT TRK repeats the current track when it has reached the end. RPT FLD repeats playing of all the tracks in the current folder. RPT ALL repeats all the tracks in the media.
INTRO Intro-play, INT indicator will be shown on the LCD display. When in this mode, the radio will play the beginning 10 seconds of each track (intro) then skip to the next track, and again, play only the beginning 10 seconds. When the listener finds a desirable track, press the INTRO button again to cancel intro-play.
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.
FLV/ FLA Previous folder and next folder.
There is a BROWSE feature that allows the user to cycle through the available media by folder, then filename to choose a song — press the BAND button to select this mode — the rotating the volume knob scrolls through the track list and pressing the volume knob selects the desired choice.

Reset – Software / Hardware

Soft Reset – MENU — RESET: If the user is not sure if settings on the radio had been altered inadvertently, restoring the factory default settings may help. Upon a reset, factory default settings will be reloaded overwriting current data, and the user should notice that all preset values will be set to default (lost). For example, the user may need to re-scan for radio stations and store them into the presets.
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 in the system menu, accessed by ong pressing the MENU button in any mode. Settings are OFF, AUTO, 30 min, 60 min and 90 min.” OFF” is the factory default value where the radio powers off im­ mediately when the gnition 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 gnition 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 count-down timer is shown on the display using the small secondary ine of characters. in the last 5 minutes of the count-down time 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 rea­ sons. It also prevents the battery from being drained if the radio s left turned on for an extend­ ed period. 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 func­ tion and must be connected to the radio.

Tips

This unit will not display non-English characters such as E and o. Non- displayable character may be shown as asterisk.’?”.
Many RDS functions do not show an immediately apparent effect. For example, the user will only notice TP when a traffic announcement is being broadcast. If in doubt, the user is ad­ vised to use the default settings. Many functions on FM RDS permit the radio  to automatically change tuning frequency.

Wiring Notes

Connections to be made to the rear of the unit during installation.
Connector A pins:
Ad. B+ or BATT +12V
When the radio is turned on, electric power is supplied to the internal electronics of the unit through this pin. Main consuming blocks such as audio power amplifier and backlights draw power from this pin. Ensure the connecting wire has minimum AWG14 wire gauge to carry the current.
AS. 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. If connected properly, such ancillary equipment will power on automati- cally in sync with the radio.
AT. ACC or +12V IGNITION KEY INPUT
Normally connects to the ignition key circuit. By sensing the voltage on this pin, the unit is able to automatically power on and power off using the input from the ignition key switch.
A8. CHASSIS GROUND (EARTH)
All electric current from this pin is combined to complete the power supply circuit. Ensure the connecting wire has 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

Connector B pins (loudspeakers pins):
B1. REAR RIGHT (+)
B2. REAR RIGHT (-)
B3. FRONT RIGHT (+)
B4. FRONT RIGHT (-)
BS. FRONT LEFT (+)
B6. FRONT LEFT (-)
B7. REAR LEFT (+)
B8. REAR LEFT (-)

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 overcurrent. Under-rated fuses can blow even if a fault condition does not exist.

Mounting Notes

Fitting the Radio
Fit the mounting cage (sleeve) into the vehicles’ ISO / DIN slot and bend the fixing tangs to lock it in place.
Connect the wiring to the rear of the radio.
Slide the radio into the cage until it “clicks” into place on the locking clips.
Fit the bezel (trim ring) on the front of the radio.
Check correct operation of the radio.

Removing the Radio

Slide the Release Keys centrally along the two sides of the radio to release the locking clips.
Slide the radio out, keeping the Release Keys in place.
Once the radio is out disconnect all the wiring and remove the radio completely.
If necessary bend the fixing tangs inward to remove the mounting cage as well.

Fitting the External Microphone
The Bluetooth radio models may be supplied with an external microphone this will be either a
panel mounted unit with a M8 stud or a visor clip.
Panel mounted M8 stud:
Find a suitable location as close to the front of the user as possible. Drill a 8.5 to 9mm hole for the mounting stud, run the cable through this and route it to the radio.
Fit the star washer and the M8 nut to hold the microphone in place.
Visor mounted:
Find a suitable location as close to the front of the user as possible. Clip, or use an adhesive pad to mount the microphone, and route the cable to the rear of the radio.
When routing the cable back to the radio be careful of sharp edges and pinch points that may damage the cable.
Make sure the cable and microphone do not interfere with any control operation or compromise the users view.
