1.7 TRANSMISSION
1. Perform steps 1 through 3 of RECEPTION.
2. Before transmitting, monitor the channel and make sure it is clear.
3. When receiving a signal, wait until the signal stops before transmitting.
The transceiver cannot transmit and receive simultaneously.
4. Press the [PTT] (push-to-talk) switch to begin your transmission.
To confirm transmission in progress the LED illuminates RED,
and TX is displayed on the LCD.
5. Holding the transceiver 1 inch from your mouth speak slowly and
clearly into the microphone.
6. When the transmission is finished, release the [PTT] switch.
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. 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. Select the desired channel using the [UP/DOWN] buttons.
3. When receiving a signal the LED indicator illuminates green,
and "RX" is displayed on the LCD.

1.8 Additional features
The HT700 Series incorporates some additional features that can be
of positive benefit to your organisation. These features can be set-up
and accessed in a number of different ways using any one of the
programmable buttons. Please contact your dealer to discuss your
exact requirements.
1.9 VOX Voice operated transmit
Any one of the programmable buttons can be assigned to access
the VOX feature.
In VOX mode the transceiver will react to your voice and transmit
automatically without you having to press the PTT button.
There is always a slight delay for the electronic switching, and
consideration will need to be given.
To get optimum performance from the VOX feature you should
use a noise cancelling headset or earpiece microphone
(see accessory options marked VOX)

2.0 BATTERY CHARGING
1. Connect the CWC640 AC
adaptor to the CCA640
charger pod. The LED
status light will illuminate
green indicating ready for
charge.
2. Turn the transceiver off.
3. Insert the battery pack
into the CCA640 pod, either with or without the transceiver attached.
The LED status light changes from green to RED and trickle charge
begins.
4. A fully discharged battery pack will take approximately 6 hours to
charge, depending on the remaining power condition.
When charge is complete, the LED status light turns green.
NOTE : The CWC640 AC adaptor can be replaced by the CMC640
12v charger cable. Charge time remains at 6 hours.

the transceiver attached. The LED will illuminate red to indicate rapid
charge in progress.
4. Charge time for a fully discharged battery pack will take up to
120 minutes. On completion the LED turns green.
2.2 BATTERY INDICATOR

battery pack and gives an indication on the LCD:
3 Segments : 14hours
2 Segments : 1hour
1 Segment : 20mins
Figure 6. Battery Indicator

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.
DO NOT INCINERATE
Do not dispose of your CNB640 battery in a fire or incinerator.
The heat of fire may cause battery cells to explode and/or release
dangerous gases.
DO NOT SHORT BATTERY PACK TERMINALS
Shorting the terminals that power the transceiver can cause sparks,
severe over heating, 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.
DISPOSE OF BATTERY PACKS PROPERLY
2.3 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:
