1.6 RECEPTION

1. Turn the transceiver on by rotating the volume control in a clockwise direction. A power-on tone is generated after 1 second to indicate the transceiver has passed its self-diagnostic test. During standby, the LED indicator will pulse amber every 3 seconds. Select the desired audio level by further rotating the control clockwise. After power on, the transceiver will always default to the last channel selected.
2. Turn the squelch control fully counter-clockwise, then rotate clockwise until the white noise stops. This condition is known as the "squelch threshold". If the control is turned clockwise past this point, weak signals may not be received. No noise or signal is heard until a signal is received that exceeds the squelch threshold.
3. Select the desired channel using the [UP/DOWN] buttons. A full listing of channels can be found on page 22. Sometimes, a slight adjustment of the squelch threshold is needed as some channels have a higher noise level than others.
4. When receiving a signal, the LED indicator illuminates green. A "RX" indication is also displayed on the LCD.

1.7 TRANSMITTING

1. Perform steps 1 through 3 of RECEPTION.
2. Before transmitting, monitor the channel and make sure it is clear.
3. For communications over short distances, press the [H/L] key and select low power (1 watt). Transmitting on 1 watt prolongs battery life and should be selected whenever possible.
4. When receiving a signal, wait until the signal stops before transmitting. The transceiver cannot transmit and receive simultaneously.
5. Press the [PTT] (push-to-talk) switch to begin your transmission. To confirm transmission in progress, the LCD indicator illuminates TX and the LED illuminates RED.

3.1 BATTERY SAFETY

The battery pack of your transceiver contains lithium-Ion cells. This type of battery stores a charge powerful enough to be dangerous if misused or abused, especially when removed from the transceiver. Please observe the following precautions detailed on page 19.

DO NOT SHORT BATTERY PACK TERMINALS

Shorting the terminals that power the transceiver can cause sparks, severe overheating, burns, and battery cell damage. If the short is of sufficient duration, it is possible to melt the battery components. Do not place a loose battery pack on or near a metal surface or objects such as paper clips, keys, tools etc. When the battery pack is installed on the transceiver, the terminals that transfer current to the transceiver are not exposed. The terminals that are exposed on the battery pack when it is mounted on the transceiver are charging terminals only and do not constitute a hazard.

DO NOT OVERCHARGE

When using the CWC640, do not charge the transceiver for more than 8 hours. Heat generated by overcharging can shorten battery life and cause other battery pack component failures.

DO NOT INCINERATE

Do not dispose of your CNB840E battery in a fire or incinerator. The heat of fire may cause battery cells to explode and/or release dangerous gases.

DISPOSE OF BATTERY PACKS PROPERLY

Lithium-Ion battery packs must be recycled or disposed of properly. For requirements in your area, check with the dealer from whom you purchased your transceiver. ♻️
