5.11 Frequency Scanning
Frequency Scanning is an optional feature that allows one MCU to scan multiple frequencies (the current limit is
12). This feature allows one MCU to operate from any one out of many different OCUs transmitting on different
frequencies.
Frequency scanning may be combined with TDMA, and MAC or SAC.
This feature is likely to be used where TDMA is not needed, or where the number of OCUs on air exceeds the
TDMA allocation per frequency.
This feature is available on all MCUs.
For example, an MCU running frequency scanning of eight frequencies each running with OCUs running TDMA
with seven slots could seek and lock onto a valid address from 56 (= 8 X 7) OCUs.
5.12 Talkback and LCD Display Resolution
Talkback is an optional feature.
Talkback may be directed to LEDs, the buzzer, and (if fitted) the LCD display and backlighting as well.
For LRC-M and LRC-L OCUs fitted with the optional LCD display, this display has a resolution of 128 x 64 pixels
and is divided into eight lines. The first and last lines are reserved for system status messages, and the remaining
six lines may be used by the user for talkback information as text, graphics, or both.
Customers have the option of having the talkback configured for them, or the flexibility of a tool to be able to
program and customize the talkback themselves.
