34 BK Radio
BUSY CHANNEL INDICATION
The yellow Busy Channel Indicator glows if there is
carrier activity on the selected channel. If the selected
channel is a Channel Guard channel and the proper
Channel Guard value is not detected, the Busy
Channel Indicator remains on for the duration of the
carrier activity and no message is heard. During Scan
and Priority Scan operation, the Busy Channel
Indicator glows when activity is detected on any
channel on the Scan List.
When scanning or priority scanning Channel Guard
channels with the CG (Channel Guard Disable) button
OFF and activity has been detected, the Busy Channel
Indicator glows for the time period necessary to
determine if the proper Channel Guard value has been
received. This will cause the Busy Channel Indicator to
flash at various rates.
BUSY CHANNEL LOCKOUT
The Busy Channel Lockout feature applies only to
those channels programmed with a receive Channel
Guard value. When carrier activity is detected on the
channel selected, the radio checks the receive
Channel Guard value. If the proper Channel Guard
value is present, the radio can transmit on that channel
even if the CG button is off.
If the radio detects an incorrect value or carrier activity
only, the transmitter is disabled. If an attempt is made
to transmit, an alert tone will be generated and the
display will show the word
BUSY
until the channel
becomes available or the PTT switch is released,
whether the CG button is on or off.
Channels not programmed with a receive Channel
Guard value can be used to transmit regardless of
carrier activity.

RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES
AND OPERATING INSTRUCTIONS
To control exposure to yourself and others and to ensure compliance
with the RF exposure limits, always adhere to the following procedures.
Guidelines:
•
User awareness instructions must accompany device when
transferred to other users.
•
Do not use this device if the operational requirements
described herein are not met.
Operating Instructions:
•
Transmit no more than the rated duty factor of 50% of
the time
. To transmit (talk), push the Push-To-Talk (PTT)
button. The red LED will illuminate when the radio is
transmitting. To receive calls, release the PTT button. The
red LED will extinguish when the radio stops transmitting.
Transmitting 50% of the time, or less, is important because
this radio generates measurable RF energy exposure only
when transmitting (in terms of measuring for standards
compliance).
•
Transmit only when persons around the vehicle are at
least 3 feet (90 centimeters) away from the vehicle with a
properly installed antenna
. This separation distance will
ensure that there is sufficient distance from a properly
installed (according to installation instructions) externally-
mounted antenna to satisfy the RF exposure requirements in
the standards listed above.
