1. On/Off & Volume Control: Turns the beltpack power
on and controls headset volume.
2. Intercom Buttons: Assignable for several types of
operation, including talk only, listen only, talk with autolisten, and all-call (where activating the key also activates all keys to the left of that key). Keys feature
momentary or latching operation. For momentary operation, the operator presses and holds a key while communicating, then releases it when finished. For latching
operation, the operator taps a key to turn it on, then taps
it again to turn it off. Latching can be disabled via software options in the base station or from AZedit. Two bicolor (red and green) LED indicators for each key provide indications for talk on/off, listen on/off, incoming
call, busy (for keys assigned to talk to IFB’s), and in-use
(for keys assigned to talk to either IFB’s or ISO’s).
3. Copy and Scroll keys: Used for key and setup page
assignment. Can also be used to talk to any location in
the intercom system when no intercom key is assigned.
(Note: There are 4 setup pages. Each contains a complete set of key assignments.)

Rack Mounting
The rack mounting brackets come with each RKP-4. These
brackets may be used to mount a single base station in a 19” wide
rack or mount two base stations side by side in a rack. Figure 5-1
shows the three brackets that come with a base station.
Figure 5-1
Rack Mount Brackets
Rack Mounting Two Base Stations
Side-by-Side
1. Remove the four pan head screws (two on each side)
closest to the front panel.
2. Place the double unit side brackets on the sides of the
base stations you wish closest to the edge of the rack.
3. Replace the two pan head screws and use a third pan
head screw (2 supplied with base station) to screw unto
the upper middle location of the rack mount middle
bracket.
4. Place the dual bracket on the other sides of the base stations. Make sure the bracket is flipped so the front bend
is toward the front of the base station. As you face the
rack, the right base station will have the middle bracket
front bend high and left base station will have the bend
low.
Rack Mounting a Single Base Station
1. Remove the four pan head screws (two on each side)
closest to the front panel.
2. Place the double unit side bracket on the side of the base station you wish closest to the edge of the rack.
3. Replace the two pan head screws and use a third pan head
screw (2 supplied with base station) to screw into the
upper middle location of the bracket.
4. Place the single unit rack mount bracket on the other
side of the base station.
5. Replace the two pan head screws and the other pan head
screw that came with the base to secure the bracket.
Screw the third screw into the upper middle hole of the
bracket.
6. Use the rack mount screws (not supplied) to secure the unit to
the rack.
5. Replace the two pan head screws and the other pan head
screw into the upper middle hole of each bracket.
6. Use the four flat head screws (2 supplied with base station) to secure the top and bottom of the middle brackets together.
7. Use rack mount screws (not supplied) to secure the unit to
the rack.

Antenna Connection
The base station is supplied with two (2) antennas.
One 1/2-wave antenna for Transmit and one 1/2-wave for
Receive. The antennas have TNC male connectors.
The frequency range of the antennas should match the receiver and transmitter of the base station. Match the color code on
the antenna with the color code on the base station.
Attach the transmit 1/2-wave antenna to the antenna input
receptacle labeled “TRAN” on the right side of the rear panel.
The antenna should be vertically aligned.
Figure 5-4
Attaching Transmit 1/2-Wave Antenna
Attach the receive 1/2-wave antenna to the antenna input
receptacle labeled “RCV” on the left side of the rear panel.
The antenna should be vertically aligned.
Figure 5-6
Vertically Polarized Antennas
Distance between Antennas
The distance between the base station’s receive and transmit
antennas is not adjustable when the antennas are connected
directly on the back of the unit.
The antennas can be remoted for better signal path. A Telex
coax assembly with remote antennas may be required. See
“Accessory and Replacement Parts” section for ordering
information.
NOTE: If your base station is to be located in a shielded rack
mount enclosure or other poor RF location, you must remote
the 1/2-wave antennas with coax assemblies. See
“Accessories and Replacement Parts” section for remote
mounting hardware.
Antenna Placement
Proper antenna placement probably has the most effect on
your TELEX Wireless Intercom System’s overall performance. The following suggestions will result in optimum performance.
Attaching Receive 1/2-Wave Antenna
Figure 5-5
Antenna Polarization
The Telex Wireless Intercom System is “Vertically Polarized”.
This means both the transmitting and receiving antennas should
operate in the vertical position.
Proper placement of the beltpack can be critical. The antennas
should be in the open. Bending the antennas up and placing
the beltpack in a pocket, etc., will reduce system distance.
It is suggested that the unit be worn on the belt or pocket with
both antenna’s vertical for best operating range and performance.
Figure 5-7
Proper Dressing of the Antennas
5-3
Keep the distance between the base station and the beltpacks
as short as possible. The greater the distance, the weaker the
signal. Make sure the “signal paths” between the base station
and beltpacks are unobstructed. You should be able to visibly
locate the base station antennas at all times for best performance.
Attempting to operate the wireless intercom system through
or around walls, ceilings, metal objects, etc. will reduce system range and performance.
Distance Between base station and beltpack
Figure 5-8
Operating System Near Obstructions
Figure 5-10
DO NOT - mount the base station 1/2-wave antennas on, or
next to metal, such as beams, walls with metal studs, equipment racks, etc. This also applies to the antennas when assembled directly to the Base Station. This will “detune” the antennas which can result in noise or loss of RF signal at the base
station.
Keeping the distance from the base station and beltpack as
short, and unobstructed as possible will produce the most reliable performance.
The base station is supplied with two antennas. This should
provide satisfactory system performance in most applications.
System range can be enhanced by remoting the 1/2-wave
antennas.
