Turn POWER/VOL knob to adjust the volume. Pressing the MONI key will provide noise so that the volume can be adjusted accordingly. Now if the radio receives a signal with CTCSS/CDCSS matching with that set in the radio, the speaker will output audio.  To Transmit 1. Press the UP or DOWN key to select the desired channel. 2. To avoid interfering with other users, press the MONI key to monitor activities on your channel and make sure the channel is idle before transmitting. 3. To transmit, press and hold the PTT button, speak clearly into the microphone with the radio 2 to 4 inches away from your mouth. To receive, release the PTT button. When the PTT button is pressed, the red LED will Light until the PTT button is released or until the transmit time out timer expires.
11 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:
12 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:
13 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.
14 Troubleshooting Guide Please check the following items before requesting service. 1. Review operation procedures. 2. Replace or recharge the battery. 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. Optional Accessories  Earphone  Speaker mic  Headset (many options)  Leather Case 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.
