Setting up the Repeater
Safety measures for installation
Note the following precautions when installing this repeater:
Use good engineering, proper grounding and protective devices to protect the repeater from power surges,
lightening and electrical damage via the power and external antenna connections.
Do not install the repeater in a place where there is extreme vibration, where there is a lot of dust, excessive
humidity or high temperature, or where it is exposed to direct sunlight.
Install the repeater in a well ventilated position, so heat dissipation is not obstructed. The heat sink becomes
hot when transmitting for long periods of time.
Do not place any objects on top of the repeater.
Note that there is a risk that hum and noise may be introduced, depending on the installation conditions and
the external power source used.
Installing the repeater
Place the repeater on a flat and level rack or shelf, with its bottom side down. We recommend securing the
wings of the repeater front panel to the equipment rack or shelf with bolts.
z Mounting on rack or shelf
z Mounting on a desk
When using the repeater
in a desktop location instead of a rack or shelf,
attach the four supplied
legs onto the bottom of
the repeater case.
About electrical grounding
The DR-2X/DR-2XE repeater, like any other communications apparatus, requires an effective ground system
for maximum electrical safety and best communications effectiveness. A good ground system can contribute
to station efficiency in a number of ways:
• It can minimize the possibility of electrical shock to the
operator.
• It can minimize RF currents flowing on the shield of
the coaxial cable and the chassis of the repeater.
Such currents may lead to radiation, which can
cause interference to home entertainment devices or
laboratory test equipment.
• It can minimize the possibility of erratic repeater/
accessory operation caused by RF feedback and/or
improper current flow through logic devices.
To prevent damage from lightning,
atmospheric electricity, electrical shock,
etc., provide a good earth ground.
Use a short, thick, braided
cable to connect your
station equipment to
the buried ground rod
(or alternative earth
ground system).

After completing the input frequency, the input popup screen automatically disappears and the input frequency
is set.
Input the downlink frequency in the same way.
Touch [Back] to return to the operation mode screen, and touch [B SETUP] on the bottom of the screen to
display the CH-B frequency set up screen, then set the uplink and downlink frequency.
Even if the CH-A and CH-B uplinks are set to different frequencies, setting the downlink to the same frequency,
makes it possible for all members to hear the conversation at the same downlink frequency whatever the uplink
frequency is used.
Select downlink antenna
Normally, downlink of CH-A outputs to the CH-A TX Antenna Terminal and the downlink of CH-B outputs to the
CH-B TX Antenna Terminal. Both CH-A and CH-B downlinks may output to the CH-A TX Antenna Terminal.
This setting allows to operating the downlink frequency with the same antenna.
How to set up the downlink antenna terminal:
1 Touch [B SETUP] to display the CH-B frequency set up screen.
The setup mode screen will appear.
2 Press “DOWN LINK” in the CH-B frequency set up screen, “DOWN
LINK” will be changed to “DOWN LINK TO ANT-A” and CH-B downlink
signal will be output to CH-A.

Since the DR-2X/DR-2XE has only one transmitter, even if the downlink frequency is set separately, the signal will not
be transmitted simultaneously.

4. Set up Priority Channel
Priority Channel
In the dual receive function, one channel may be set as the priority channel.
Normal operation mode:
• When CH-A and CH-B are set to different uplink frequencies, a signal on either uplink frequency will inhibit
reception on the other channel until the first channel communication is complete.
Priority mode:
• When receiving a signal on the channel set as Priority, even if communication is in progress on the normally
used frequency, that communication will be stopped and the emergency (Priority) communication will be
automatically transmitted.
To set the priority channel, touch [RX]/[TX] area of the prioritized channel in the operation setup screen, “PRI”
appears and this channel is set to the Priority channel.
To deactivate the Priority channel, touch the same area to unset PRI and return to normal operation.
Priority mode Normal operation mode
The uplinks may be received simultaneously, but since the DR-2X/DR-2XE has only one transmitter, even if the downlink
frequency is set separately; the signals may not be transmitted simultaneously.
In the FIX (Digital C4FM) mode, when CH-A or CH-B is set to Priority, a received C4FM digital signal
including the registered DG-ID will have precedence over signals received on the other channel.
In the AUTO mode, this channel will have precedence when receiving a C4FM digital signal including the
registered DG-ID or when receiving an FM signal including the registered CTCSS.
Transmissions are not interrupted, even if other signals are received on the priority channel.

5. Set up Other Functions
Adjusting the squelch level
z When the squelch level is set to “open” the repeater will transmit, so the TX output must be connected to the duplexer
and antenna.
z Use extreme caution when making the squelch adjustment or measurement with a signal generator. Do not connect
the signal generator to the duplexer antenna port. To avoid damage to the test equipment, always connect the signal
generator directly to the RX antenna connector on the DR-2X/DR-2XE.
z While the squelch level is being set, repeater transmit operation is temporarily permitted. This will facilitate checking
the performance of the Duplexer, and allow evaluation of the receiver sensitivity degradation (“desense”), during
simultaneous transmit/receive operation.
1 Touch [A SETUP] or [B SETUP].
The setup mode screen will appear.
2 Touch [SQL].
When [SQL] turns yellow, the VOL meter below the RX band frequency
display, will change to the SQL meter and show the squelch level
setting.
3 Touch [▲] or [▼] to adjust the squelch level.
The level will be displayed in the SQL meter.
4 Touch [BACK].
The squelch level is set, and the display will return to the operation
mode screen.
