Motorola MT2000 用户手册

Refer to your radio service manual for the transmit VCO crossover alignment procedure. This procedure should
only be performed by qualified service personnel.

Transmit deviation limit alignment is a way of correcting for deviation sensitivity versus RF frequency variations in
the VCO. The transmit and receive bands are divided into frequency zones with a calibration point (value) in each
zone. Compensation for each of these points must be checked and adjusted if the VCO is replaced.

F1 -  HELP provides useful information about the currently displayed menu, screen, or field.

F6 - TOGGLE PTT function will alternately key and dekey the radio being serviced.

F8 -  PROGRAM VALUE function will program the selected value into the radio.

F10 - EXIT moves the display backward in the RSS tree, one screen or menu at a time.
