Changing Operator Menu Parameter Values
When changing an operating parameter, line 2 describes the parameter and line 3 offers the available choices:
RF OUTPUT POWER
OFF
LOW MID HIGH MAX
The cursor (underscore) shows that the transmitter output is switched off. The operator can change the current condition (displayed
line 3) by using the Left Arrow < Å > or Right Arrow < Æ > keys, moving the cursor under the desired transmit output power level,
followed by pressing the < OK > key to accept the chosen parameter. If the user doesn’t confirm his choice by pressing the < OK >
key, or uses the Up Arrow < Ç > or Down Arrow < È > keys, the operating parameter change is cancelled; the current parameter is
not modified. This is a convenient “escape” feature.
Certain operating parameters are entered values (not selected values). For example, the frequency is displayed as follows:
FREQUENCY
6434.50 MHz
To change the current value of this parameter, the operator presses < OK >, entering the Menu Edit mode, so the cursor appears
under the first figure of the displayed frequency, as follows:
FREQUENCY
6
434.50 MHz
The frequency value is changed by the following steps: (1) move the cursor to the appropriate figure using the < Å > and < Æ >
keys; (2) increment or decrement the selected figure using the < Ç > and < È > keys. For example:
FREQUENCY
643
4.50 MHz
The frequency value to the right of the decimal point is a fractional MHz value, selected in steps of 250 KHz (.25 MHz). Repeat the
operation (previously described) to increment or decrement this value. To increment to a frequency of 2450.50 MHz, move the
cursor to the right of the decimal point, then press the < Ç > one time:
FREQUENCY
6454.50
MHz
After modifying all of the necessary digits, the operator must validate the chosen frequency by pressing < OK > and closing the
Menu Edit mode, changing the operating frequency.
FREQUENCY
6454.25
MHz
If you make a mistake while setting a number and you want to restore the previous value, don’t validate your
modifications: simply wait during 30 seconds without touching the keypad. The system will automatically exit the edit
mode without saving the modifications; the display returns to the status screen.
