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 HT800 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 OPTIONAL TRICKLE CHARGER-model CCA230
1. Connect the CWC640 AC
adaptor to the CCA230
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 CCA230 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.

3. Insert the battery pack into the CSA640E charger, either with
or without 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
For your safety and convenience your transceiver continually
monitors the 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 CNB840E 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:

FOR USA VERSION:-
2.6 SAFETY TRAINING INFORMATION
WARNING.
Your Entel radio generates RF electromagnetic energy during transmit
mode. This radio is designed for and classified as "Occupational Use Only",
meaning it must be used only during the course of employment by
individuals aware of the hazards, and the ways to minimize such hazards.
This radio is NOT intended for use by the "General Population" in an
uncontrolled environment.
Use only Entel approved accessories. Use of accessories other than those
specified may result in RF exposure levels exceeding the FCC requirements
for wireless RF exposure.
CAUTION.
To ensure that your exposure to RF electromagnetic energy is within the
FCC allowable limits for occupational use, always adhere to the following
guidelines:-
ඖDO NOT operate the radio without a proper antenna attached, as this
may damage the radio and may also cause you to exceed FCC RF
exposure limits. A proper antenna is the antenna supplied with this radio
by the manufacturer or antenna specifically authorized by the manufacturer
for use with this radio.
ඖDO NOT transmit for more than 50% of total radio use time
("50% duty cycle"). Transmitting more than 50% of the time can cause
FCC RF exposure compliance requirements to be exceeded.
The radio is transmitting when the "TX indicator" lights red.
You can cause the radio to transmit by pressing the "PTT" switch.
