transmit on a channel fixed in the “Secure” mode by
programming, “SEC ONLY” is displayed and trans-
mitting is not permitted. Conversely, if the “Secure”
mode is selected and the channel is fixed in the
“Clear” mode, “CLEAR ONLY” is displayed and
transmitting is not permitted.
If your transceiver has encryption, consult your
system operator for more information on how it func-
tions in your application.
Encryption (Hardware) Keys
NOTE: A nearly constant power source must be
applied to the radio to maintain the encryption keys in
memory. Therefore, when changing the battery, be sure
to reattach another battery within one minute. If it is
not, these keys may be lost and will need to be
reloaded again.
Each channel programmed for encryption has an
encryption key associated with it. Up to 16 keys can
be loaded into the radio, and the location from 0-15
refers to the “Hardware” location of the key. If more
than one key is loaded, the Hardware Key Select
option key may be programmed to select another key
for a channel. A new key selection remains in affect
until it is manually changed again. Select a hardware
key as follows:
1. Press the Hardware Key Select key or select that
menu parameter and HWKEY x is displayed (“x” is
the current key selection from 0-15).
2. Press the Up/Down switch to display the desired key
and then press the Hardware Key Select key again or
F2 key to select it and return to normal operation.

Option Keys
Almost all the transceiver keys are programmable
unless they are dedicated to a specific function. These
keys can be programmed by your system operator for
one set of functions in the Conventional mode and
another in the SMARTNET/SmartZone mode as
described on page 10. Table 5 on page 12 lists the
programmable keys, the functions that can be
programmed in each mode, and the page of this
manual on which the function is described.
Menu Mode
Most functions that can be controlled by an
option key can also be controlled by the menu mode.
An exception is Keypad Lock which can be controlled
by an option key only. The functions that can be
controlled by the menu mode are also shown in Table
5 on page 12. Only parameters that apply to the
selected channel type (Conventional/SMARTNET/
SmartZone) are displayed.
When the menu mode is used, the F1 and F2 keys
become dedicated menu mode control keys: F1 is
Back/Clear, and F2 is Menu Select/Enter. If the menu
mode is disabled, these keys can be programmed for
other functions. The menu mode operates as follows:
1. To select the menu mode, press the F2 key. Up to
three menu parameters are then displayed as shown
in the preceding illustration.
2. To scroll up or down through the menu parameter
list, press the Up/Down switch. The selected
parameter is indicated by a dark bar.
3. To display the available modes for a highlighted
parameter, press the F2 key. The currently selected
mode is indicated by an asterisk.
NOTE: Some parameters cannot be selected with
scanning enabled.
