If "PASSWORD" is briefly displayed when
power is turned on and you are prompted to enter a
password, the Power-Up Password feature is enabled.
Refer to Section 3.2 for more information.
If "UNPROGRAMD" is displayed, the cause
could be any of the following:
An unprogrammed channel is selected. Select a
programmed channel.
The selected channel is programmed for an option
that is not installed or an error in programming was
detected. Reprogram the radio.
If no characters appear in the display, the battery
may be discharged or defective. Try another battery. If
some other problem is occurring, turn power off and
then on again to reset the control logic. Also make
sure that the controls are properly set. If it still does
not operate correctly, return it for service.
NOTE: There are no user-serviceable components in
the transceiver. Altering internal adjustments can cause
illegal emissions, void the warranty, and result in
improper operation that can seriously damage the
transceiver.
