Each of these channels can be individually programmed with operating frequency (pgs. 27), subaudible tone encoder or tone squelch and its tone frequency (pgs. In addition, a total of 10 memory banks, A to J, are available for usage by group, etc. *except for scan edge memory channels. D Using the [Y]/[Z] keys MR/CALL Y/Z z Push [BAND] to select the desired band as the main band. c Push [Y] or [Z] to select and set the desired memory channel. · Pushing [Y]/[Z] for 1 sec. · If scan is activated, push [Y]/[Z] again or push [CLR A(MW)] to stop it.

MAIN TX D Using the keypad MR/CALL z Push [BAND] to select the desired band as the main band. v Push 3 appropriate digit keys to input a channel number. · Blank channel can be selected. · Push only 1 appropriate digit key, [MONI 1(BANK)], [SCAN 2(T-SCAN)], [PRIO 3(PTT-M)], [HIGH 4(DTCS)] or [MID 5(DTCSS)] then push M [M(TONE-1)] or [SQLZ #(16KEY-L)] to select scan M edge channels. "M" and "#" can be used for "A" and "b" respectively. Y/Z w Rotate the same band's [DIAL] to select the desired memory channel. · Programmed memory channels only can be selected. M "!" appears 29 MEMORY OPERATION 5 I Programming a memory channel VFO settings, including the set mode contents such as subaudible tone frequency, offset, can be programmed into a memory channel. w Push the same band's [M/CALL·MW] for 1 sec. · 3 beeps sound · "!" indicator and the memory channel number blink. eRotate the [DIAL] to select the memory channel to be programmed. · Memory channels not yet programmed are blank. r Push the [M/CALL·MW] for 1 sec. to program. · 3 beeps sound · Memory channel number automatically increases when continuing to push [M/CALL·MW] after programming. 5 CONVENIENT Memory programming can be performed in versatile ways e. g. memory channel to the same (or different) memory channel, memory channel to the call channel, etc. [EXAMPLE]: Programming 145. 870 MHz into memory channel 20 (blank channel) via the controller.
