MAINTENANCE
Refer to a Regency Sales/Service Center for
servicing. The transceiver should be checked semi-
annually for proper operation.
WARNING: FCC regulations require that any repairs
and/or adjustments made to the transmitter of this
radio to be rendered under the supervision of a
technician holding a general radiotelephone license.
DO NOT TAMPER WITH INTERNAL ADJUSTMENTS.

DESCRIPTION
The RH256 and RU156 are sixteen-channel land
mobile transceivers. The RH256 operates in the VHF
frequency range in three bands. The RH256A operates
from 134 to 150 MHz; the RH256B operates from 150
to 162 MHz and the RH256C and RH256UK both operate
from 162 to 174 MHz.

work in systems having 12.5 KHz channel spacing with
a maximum system deviation of +2.5
KHZ.
The RU156 operates in the UHF frequency range,
also in three bands. The RU156A operates from 421.4
to 450 MHz; the
RU156B
operates from 450 to 462 MHz,
and the RU156C operates from 462 to 512 MHz.
The radio can store up to sixteen channels with-
out battery backup.
All radios
ctnne
with CTCSS tone
and scanning capabilities. A monitor switch and a
night/day switch are also standard.
(Refer to Figure 1 for the following descriptions.)
VOLUME CONTROL/ON-OFF SWITCH
This control varies the speaker volume. Clock-
wise rotation turns the radio on and increases the
volume. When the radio is turned off and back on it
will revert back to the state it was in before being
switched off. The radio will remember the last
state it was in even if the power plug is dis-
connected.
SQUELCH CONTROL
The squelch control is used to eliminate the
speaker noise when not receiving a transmission.
Move
the control clockwise until noise is heard (if in the
SCAN mode the receiver will stop scanning).
Then
move the control counter-clockwise until the speaker
noise is squelched (if in the SCAN mode the receiver
will start to scan approximately two seconds after
the speaker squelches).

DESCRIPTION (Continued)
MONITOR SWITCH
Placing this switch in the
"MON"
position
allows the user to monitor the channel when the
CTCSS decoder is operating.
NIGHT/DAY SWITCH
Placing this switch in the "DAY" position
places the display lights at maximum luminosity and
does not light the keyboard. In the "NIGHT" position
the display light's luminosity is decreased and the
keyboard is illuminated.
STATUS LEDs
There are four status LEDs located to the left
of the channel display.

PRIOR
activated. This is accomplished by removing
the microphone from the hang-up clip
(off-
hook condition) and pressing the push-to-talk
switch on the microphone.
When lit indicates that the radio is in the
SCAN mode. Pressing the SCAN button on the
keyboard puts the radio in the SCAN mode.
When lit indicates that a message has been
received. The radio's CTCSS decoder must be
activated in order for this LED to function.
If a message has been received, going off hook
or changing the channel will reset the LED
to its OFF state.
When lit indicates that the radio's priority
function has been selected. Pressing the
Prior button on the keyboard will activate
and deactivate the PRIORITY function.

CHANNEL DISPLAY
Displays the current channel the radio is
operating on. The channels are selected by pressing
the appropriate button(s) on the keyboard.
IV.
INSTALLATION
The radio is designed for mobile operation in
a vehicle with a 12V negative ground system. The red
wire (with in-line fuse) is connected to the positive
battery terminal and the black wire connected to the
negative battery terminal.
Mount the radio in an accessible but not cramped
area. Allow a few inches clearance on the right side
to allow the transmitter's heat to dissipate.
Mount the microphone hang-up clip in a con-
venient location making sure the clip is grounded.
In many new vehicles with a plastic dashboard, it
may be necessary to add a ground wire to the clip to
insure a good ground connection.
It is recommended that the radio and antenna
installation be performed by a technician experienced
in two-way radio installation.
WARNING: The FCC requires that the transmitter be
adjusted and set on frequency by a technician holding
a general radiotelephone license.
I
NOTE: The transceiver is equipped with reverse
polarity protection. In the event that power leads
are reversed the fuse will blow; connect the power
leads to the correct polarity and install a new
SA fuse.
