2. A “click” indicates the BELT CLIP is locked into position.

Battery Installation

1. Release the BATTERY COMPARTMENT COVER LATCH located on the rear side of the unit (see Figure 3) and remove the BATTERY COMPARTMENT COVER from the BATTERY COMPARTMENT (See Figure 4).
2. Install 3×1.5V AAA alkaline batteries or Ni- MH rechargeable batteries (not included) as shown.
3. Reinstall the BATTERY COMPARTMENT COVER and lock the BATTERY COMPARTMENT COVER LATCH into position.

When the COMMUNICATOR is not being used, conserve battery power by pressing the I/O button to OFF. Remove the batteries if the unit will not be used for a long period.

LCD Screen

• Turning the Unit ON:
  Press and hold the button. The unit will “beep” with dual tone and the LCD SCREEN will briefly display a SELF-TEST Screen.

• Turning the Unit OFF;
  Press and hold the I/O button. The unit will “beep” with a signal tone and the LCD Screen will turn blank.

Adjusting Speaker Volume:

1. Press the Up button to increase the Speaker Volume.
2. Press the Down button to decrease the Speaker Volume.
3. The Speaker Volume level is indicated by the numbers 1 to 8 displayed on the LCD Screen.

Receiving a Signal:
The unit is continuously in the RECEIVE mode when the unit is ON and not Transmitting. When you receive a signal on the current channel, the RX icon is displayed. (See “LCD SCREEN” for details) and red LED indicator lights up.

Transmitting a Signal:

1. Check the channel activity by using the MONITOR function (See below “MONITOR” section). You’ll hear static if the channel is unoccupied. Don’t TRANSMIT if someone is talking on the channel. Press and hold the PTT button to TRANSMIT. The TX LED Indicator will light up in red. Hold the unit in a vertical position with the MICROPHONE 2 to 3 inches from the mouth.
2. While holding the PTT button, speak into the unit using a normal tone of voice.
3. Release the PTT button when you have finished transmitting.

NOTE : For other people to receive your transmission, they must also be on the same channel you are currently using. Refer to the “Changing Channels” section for more information.

Operation

The unit has 75 channels (Channel 1-80 with channels 22, and 23,61,62&63 prohibited for voice transmitting). You can communicate with any other PMR that is using the same channel. In Australia,

1. Except in an emergency, the unit must not be operated on channel 5 and 35;
2. Channel 11 is the customary calling channel for establishing communication;
3. Channel 40 is the customary road vehicle channel.

Changing Channels:
The factory default start-up channel is channel 1. Before selecting a channel for communication, always listen to it and ensure it is not already being used. Always avoid selecting a busy channel when the unit keeps on receiving a signal (the RX icon is displayed) from an unknown party.

To change channels:

1. Press the button until the current channel number flashes on the LCD Screen.
2. While the channel number is flashing:
   • Press the Up button to move to a higher channel.
   • Press the Down button to move to a lower channel.
   • The channel changes from 1 to 80, or from 80 to 1. (channels 22, and 23,61,62&63 being inhibited).
3. Press the PTT button to confirm the selected channel and return to the NORMAL mode.

NOTE : Refer to the “Channel Table” section of this Owner’s Manual for detailed frequency listings.

High/Low power selection:

1. Press twice to enter to High/Low power page.
2. Press the 4/7 button to select the power level. The LCD panel indicate “L” when low power is selected. Low power can extend the life of battery life but would reduce the talking range.

Monitor:
You can use the MONITOR feature to check for weak signals in the current channel.

1. Press the button 3 times to activate this function.
2. Press again the button to deactivate the function.

Using the Torch:
Press and hold the Torch button to shine the torch. The torch works even when the unit is switched off.

Automatic Power Save Feature:
After 6 seconds for the last operation, the PM enters the power saving mode automatically. The life of the batteries would be extended. The PM is still able to receive transmission in this mode.

Low Battery Alert:
When the batteries in the unit are low, an alert tone will be heard and the red LED will light up once every 15 seconds. Replace new batteries immediately.

Channel Scan:
CHANNEL SCAN performs searches for active signals in an endless loop from 1 to 80 (channels 22, and 23,61,62&63 being inhibited).

1. Press and hold the SCAN S button for 1 second to turn on the scan function. The channel number on the LCD Screen changes rapidly until an active signal is detected.
   During CHANNEL SCAN mode

   • Press and hold the PIT button so you can talk to others who use the same channel.
   • Press the C button to change to the CALL function and to send a CALL TONE on that active channel.
   • Press and hold the SCAN S button again for 1 second to deactivate
     CHANNEL SCAN mode

2. When an active signal (one of 80 channels) is detected. CHANNEL SCAN pauses, keeping the active signal broadcast.

3. Press the PT button to communicate through the active signal channel and CHANNEL SCAN is deactivated.

4. When an active signal (one of 80 channels) is detected, but another channel is desired, press the Up or Down button to bypass the current channel and continue to search for another active channel.

Repeater Function
A repeater facility is a third-party facility that is only available in some local areas. Only use this function for extending your communication range when you know the channel of the repeater facility in vour local area. Press the S button once to switch on/off the Repeater function.

Sending Call Tones
You can use CALL TONES to alert the others when you are attempting to contact them. You can also use CALL TONES to signal the beginning or the end of a transmission. Call tone can only be transmitted once (not more than 3 sec) in any 60 secs. It means that the unit will not transmit a call tone more than once no matter how many times you press the ‘Call’ (6) button within a minute.

1. Press the C button twice shortly, and the red TX LED indicator will light up and the CALL TONE will continue for 3 seconds.
2. Release the C button, your CALL TONES will transmit to nearby receivers set to the same channel.

Time-out Timer
The unit will disable transmitting when the PT button pressed exceeds 180 seconds.

Press the PT button again to re-activate transmitting.

• Channel 5 and 35 are for emergency calling. Please do not use these channels in non-emergency cases. + Speech telephony is inhibited on channels 22 and 23.
• Channels 1-8 and 31-38, 41-48 and 71-78 are used as repeater channels with 750kHz offset. Channels 1-8 and 41-48 are used for mobile reception and channels 31-38 and 71-78 for mobile transmission. Only use this repeater function when a long-distance communication via the local repeater facility is specifically required. Unless it is necessary, avoiding operation on locally used repeater input channels (channels 31 to 38 and channels 71 to 78) or locally used repeater receiving channels (channels 1 to 8 and channels 41 to 48) is recommended.
• Channels 61, 62 and 63 are reserved for future use. They cannot be activated until approved by the ACMA CBRS Class Licence in Australia.

Note: This product is made to the new standard 2011 version. There are possible operational issues during the changeover from the old version of 25kHz to the new version of 12.5kHz channel spacing. They include the consequences of narrowband (with 2.5kHz deviation) transmissions being received on the old wideband equipment, and wideband (with 5.0kHz deviation) transmissions being received on newer narrowband equipment. There is a possibility of interference due to the older equipment being operated on channels adjacent to new narrowband channels.
