Numeric Keypad Frequency Selection
The L3149B can be configured for controlling up to 16-frequency control with the XAC0008A C200
Programming Software. When the desired frequency is selected using the numeric keypad, that frequency
change command is sent to the base.
N OTE : Tone operation only: Other parallel units will reflect the newly selected frequency (Parallel
Status Update).
To select a frequency when nine or fewer function tones are enabled, press the corresponding button 1
through 9 on the numeric keypad. The unit automatically sends the command when the key is pressed.
 When ten or more frequencies are enabled, use keypad buttons 2 through 9 to select frequencies 2
through 9.
 To select frequency 1, press 0, then 1.
 To select frequencies 10 through 16, press 1, then press 0 through 6.
If a disabled frequency is selected, the display shows:
DISABLED FREQ
. Pressing the
CLEAR
button
exits the frequency selection mode without changing the selected frequency. To scroll through the
enabled frequencies display, press
*
to scroll down and
#
to scroll up.
After the desired frequency has been selected, the operator may:
 Press the
SELECT
button to select the frequency and exit the frequency selection mode.
 Press the
MONITOR
button to select the frequency, exit frequency selection mode, pause 250 ms and
send a monitor burst to monitor the newly selected frequency.
 Press and hold the
TRANSMIT
button or handset PTT bar to select the new frequency, exit the
frequency selection mode and begin transmitting on the newly selected frequency.
Frequency Display
When shipped from the factory, the desk set’s LCD display shows
FREQ: XX
, with XX being 1 to 16,
depending on the selected frequency.
Each time the unit is powered up, the status of the base/radio is unknown. The desk set LCD display
flashes the last selected frequency when the unit was powered down. The display continues flashing until
a transmission or frequency change is entered, or a parallel unit initiates a transmission or frequency
change.
Each time a guard tone is detected on the line, the desk set assumes the status of the base/radio is
unknown until a function tone is decoded at the proper time.
Note that the display remains flashing even when a monitor command is initiated after power-up. This is
because the monitor command does not control which frequency is being monitored and the state of the
base/radio is still unknown.
