radio or system performance.

Note: Lower power tuning is not applicable to 800 MHz or low-band

models.

1. Press F6 at the TRANSMIT POWER screen to key up the radio and

toggle PTT. The radio's RF output must be terminated into a 50

ohm load. A three-minute time-out-timer is enabled when the

radio is keyed.

Test frequency and current high and low power levels are shown

on the left side of the screen. The status bar at the bottom of the

screen shows the actual setting in relation to the minimum and

maximum settings allowed for transmission power. If an error

occurs, a pop-up message will appear to indicate the type of error

that occurred. (Refer to the list of computer-to-radio

communication error codes in the Appendix.)

2. While the radio is transmitting, modify the TX power softpot

setting using the UP/DOWN arrow keys. Use the Shift-UP/DOWN

arrow keys to increase the adjustment speed.

Note: A relative TX power value will be displayed, but you must

measure the actual RF power with a service monitor.

Use<:or <SHIFT><<SHIFT>:keys to change

and <ENTER> to go to next softpot.
