self-diagnostic test. During standby the LED indicator will
pulse amber every 3 seconds, to further verify its circuitry is
functioning correctly. 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.

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.
18
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.
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.

FOR USA VERSION: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:ඖ DO NOT operate the radio without a proper antenna attached, as this may damaged 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.
ඖ DO 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.
ඖ ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when
transmitting and only use approved accessories to ensure FCC RF exposure compliance
requirements are not exceeded. To provide the recipients of your transmission the best
sound quality, hold the transceiver at least 5 cm (2 inches) from your mouth, and slightly
off to one side. The information listed above provides the user with the information needed
to make him or her aware of RF exposure, and what to do to ensure that this radio
operates within the FCC RF exposure limits.
Electromagnetic Interference/Compatibility
During transmissions, your Entel radio generates RF energy that can possibly cause
interference with other devices or systems. To avoid such interference, turn off the radio in
areas where signs are posted to do so. DO NOT operate the transmitter in areas that are
sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as a consequence
of their employment. These persons should be made fully aware of the potential for
exposure so they can exercise control over their exposure.
Changes or modifications to this device, not expressly Approved by Entel UK could
invalidate your authority to Operate this device under FCC regulations.
