256 memory channels

Up to 256 memory channels with 12 char­acter channel names can be stored with
up to 16 banks. The rotary selector allows
you to select each bank or memory chan­nel.

Simultaneously work 2 optional
internal units

2 optional units can be installed and will
work simultaneously. You can select op­tional units to suit your needs and to pro­vide versatile usage.

Combination of available internal units

✔ Available simultaneously

1 UT-113 is available in conventional mode.
2 UT-105 and the UT-111 have to be installed

in slot 1.

* Same optional types, such as UT-109 and

UT-110, can not be installed simultaneously.

Full built-in tone-signalings

All tone-signalings are builtin such as
CTCSS, DTCS, 2-tone/5-tone and DTMF
encode/decode, so you don't need to in­stall an optional tone-signaling board. And
a wide variety of selective calling systems
are available to call specific station(s) or
control a repeater. In addition, ANI (Auto­matic Number Indication) function is avail­able with 2-tone/5-tone and DTMF.

Largest LCD in its class

With the large LCD, a simple sentence of
up to 24 full-dot matrix characters pro­vides more smooth communication than
previous one word indication. Operational
icons, such as antenna (S-meter) or bat­tery life, show various operating status at
a glance. What is more, original charac­ters can be made and indicated on the
LCD.

Durable construction

The body is compact, yet the polycarbon­ate panel and one-piece aluminum chas­sis provides durable construction to meet
MIL STD grade C, D and E for shock and
vibration. You can count on the unit to op­erate in challenging environments.

Flash ROM for system upgrades

Flash ROM is adapted as the main CPU,
which allows system customize and future
compatibility with other protocol. A newly
designed ultra high speed PLL, with a
Fractional-N system, offers faster acquisi­tion times for efficient trunking use.

Prolonged Ni-MH battery

The Ni-MH battery is designed for 10
hours operation. A battery case is option­ally available for using a set of alkaline
batteries (six AA (R6) cells) during charg­ing.

Built-in compander function

Built-in compander function provides clear
audio quality under noisy environments.

* Receiving party must have same function.

Smart design with easy opera­tion

The rounded, compact* design fits com­fortably in your palm, and is easy to carry
around. The large keypad makes one­hand operation easy.

* Size: 54(W)×139(H)×38(D) mm

Multi connector for accessories

The 9-pin multi connector, which use the
spring action for close contact, allows you
reliable operation with accessories, such
as speaker-microphone or earphone.

Other features

• The red key on the top panel can be an
emergency trigger

• Normal and priority scan functions

• Time-out timer capability

• Narrow/wide multi-band width and 2­step power save are supported

• Talk around function changes duplex
channels to simplex channel

• VOX capability and more...
