"E." Press "REVIEW" at anytime to see what frequency is programmed
there. If the review button flashes 000.0000 on the LED readout
display, you might be entering an invalid frequency. Refer to the list
of acceptable frequencies in the Frequency Range Bands below.

Push "MANUAL" to step to channel number two. Enter the frequency. Push
"E." Push "MANUAL" to step to channel three. Repeat this process until
all the (10) channels are full, or you've run out of frequencies to

seconds after the conversation has stopped.
