Features
Monitor
Press the MONI button to monitor any activity on the channel. Wait for this activity to clear before
transmitting.
Channel Scan
Channel scan is set to monitor desired activities on all channels in scan list. When channel scan is
enabled, the radio will automatically scan all channels in scan list until activity is detected on a channel.
The scanning will then stop and the receive audio will be heard.
When scanning stops on an active channel, it will restart in the preset restart mode that is set by the
dealer. Scan restart mode can be either Time operated scan or Carrier operated scan.
①Time Operated Scan
If scanning stops on an active channel, and continues to listen for a preset period (the time is preset by
the dealer), it will begin scanning other channels even if there is still activity on the channel.
②Carrier Operated Scan
Scan will lock in on the busy channel until there is no activity.
Channel Scan Operations
1. Press SCAN key
Scan starts from the current channel and then scrolls all selected channels in sequence.
2. Press UP or DOWN key to change channel scan sequence. Press the UP key; radio skips the
current channel and scans other selected channels in ascending order; press the DOWN key;
radio skips the current channel and scans other selected channels in descending order.
3. Press SCAN key again, scan stops.
4. Adding or deleting a channel in/from the scan list. The dealer can add or delete a channel in/from
the scan list. Only channels in the scan list can be scanned.
Priority Channel Scan
If your dealer has set a priority channel, when radio scans non-priority channels, it will periodically
sample the priority channel. If desired activity is detected on the priority channel, it will switch to the
priority channel for communications.
Scan Revert Channel
The scan revert channel feature allows you to transmit on the proper channel while initiating a call
during channel scan. Press [PTT] button, radio stops scanning and transmits on the revert channel.
This feature is set by the dealer.
Selectable CTCSS/CDCSS
CTCSS/CDCSS feature is used to avoid receiving unwanted signals on the same channel. When
CTCSS/CDCSS is enabled, the radio only allows audio with the same CTCSS/CDCSS code to
activate the speaker. If CTCSS/CDCSS is disabled, the radio will hear all calls on the same channel.
When the dealer allows CTCSS/CDCSS to be selectable by the end user, the operations are as
follows:
11
Press the [UP] key while holding down the [MONI] key to enter CTCSS/CDCSS set mode.
In this mode, press [UP] or [DOWN] to select CTCSS/CDCSS.
Press [SCAN], LCD display toggles between OFF/CTCSS/CDCSS/-CDCSS:
CTCSS/CDCSS OFF: 00
CTCSS:
01— 38
CDCSS:
01— 83
-CDCSS:
-01— -83
OFF
CTCSS
CDCSS
-CDCSS
Please refer to CTCSS/CDCSS table.
Press [UP] while holding down [MONI] to exit CTCSS/CDCSS mode.
Note: Though CTCSS/CDCSS feature can prevent you from receiving unwanted signals; it
doesn’t mean your calls are absolutely private.
Selectable squelch level
If this feature is enabled by the dealer, then
Press the [DOWN] key while holding down the [MONI] key to enter squelch level set mode. In this
mode, press [UP]/[DOWN] to select the level, 0—9.
Press [PTT] or [MONI] or [SCAN] to exit the mode.
High/Low power
If this feature is enabled by the dealer, then
While holding down [PTT], press [MONI] to toggle the power of the current channel between high and
low.
When the power is low, “Lo” will be displayed on LCD.
Key lock
The key lock feature is designed to avoid accidental pressing of keys. If this feature is enabled by
the dealer,
The operation procedures are as follows:
12
1, Press [SCAN] while holding down [MONI] to lock keys. When keys are locked, [UP],[DOWN]
and [SCAN] keys are inoperable, but [PTT] and [MONI] keys will still function.
2, Press [SCAN] while holding down [MONI] to unlock keys.
3, lock symbol appears on LCD:
Time Out Timer (TOT)
Time Out Timer is to prevent user from transmitting on the same channel for extended periods of time.
This also protects the radio from damage caused by accidental transmissions.
If transmission exceeds the preset time, (the TOT time can be preset by the dealer), the radio will stop
transmitting and return to the receive mode. Alert beeps will sound to indicate the halt in transmission.
Releasing the PTT button will cause the beeps stop.
Battery Save
While no activity is on channel and no operation is performed for 5 seconds, the Battery Save feature
will automatically be switched on to reduce power consumption. When a signal is received or an
operation is performed, the Battery Save feature is automatically switched off.
Low Battery Alert
When the battery voltage becomes low, the red LED will flash and beeps are sounded. You need to
replace or charge the battery.
Busy Channel Lock Out
If the selected channel is set for busy channel lock out, by your dealer, you cannot transmit when
there is activity on that channel. If you press the PTT button, the radio will sound beeps and will
stay in the receive mode.
Backlight
This feature can be enabled by the dealer.
When this feature is enabled, pressing any key except the PTT will illuminate the display. The display
will stay lit for 5 seconds.

3.
If reception is poor, check the antenna to make sure it is undamaged and operating in a vertical
position.
4.
Try another location with fewer obstructions.
5.
If you cannot communicate with your group members, make sure you are using the same
frequency and CTCSS/CDCSS.
6.
If you hear other conversations on your channel, change your CTCSS/CDCSS. Remember to
change CTCSS/CDCSS of your other group members.

Care and Cleaning
◇ Do not carry your radio by the antenna or remote microphone.
◇ Wipe the battery contacts with a lint-free cloth to remove dirt, grease, or other material that
may prevent good electrical connection.
◇ When not in use, keep the accessory jacks covered with the protective cap.
◇ If cleaning the radio housing becomes necessary, use a cloth or paper towel dampened with
a non-abrasive cleaner. Glass cleaner works well. Avoid using strong chemicals. DO NOT
submerge in water.
