FT-23R MKII OPERATING MANUAL 1
Yaesu FT-23R MK
Ⅱ
2m Hand-Held
Cpu-Controlled FM Transceiver
The FT-23R MK
Ⅱ
is an ultra compact FM hand-held for the 2m amateur band that offers
the convenience of very small size and light weight combined with the features and flex-
ibility of performance only possible with microprocessor control. A variety of recharge-
able battery packs and dry cell cases are available, providing up to five watts of RF power
output.
The transceiver is housed entirely in zinc and aluminum die-cast alloys, and battery cases
are constructed of thick high-impact polycarbonate plastic, for professional-grade rugged-
ness required in the most demanding applications. Rubber gasket seals around all external
controls and connectors keep out dust and rain or spray, assuring years of reliable opera-
tion even in harsh environments.
Standard microprocessor-controlled features included ten memory channels which each
store repeater shifts, CTCSS (Continuous Tone Controlled Squelch System) tone frequen-
cies and tone encode/decode selections*; busy channel and priority channel scanning; 1MHz
up/down stepping; plus a top panel rotary dial for memory and frequency selection. Seven
of the memories can also be programmed for non-standard repeater shifts. The LCD (Liq-
uid Crystal Display) shows six frequency digits, memory channel selection, and CTCSS
tone frequency during tone selection*, and includes a bargraph S/PO meter.
Please read this manual carefully to gain a clear understanding of the features of the FT-
23R MK
Ⅱ
.
*
: CTCSS tone features require the FTS-12 Tone Squelch Unit, optional in some countries.
