7.6 Radio Service
If the radio is not responding to any key presses, the keypad may be locked. Refer to
Section 3.6 for more information.
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 radio. Altering internal adjustments can
cause illegal emissions, void the warranty, and result in improper operation that can
seriously damage the radio.
