the event of an AC power outage, the automatic power control circuit will automatically switch the
repeater to the backup battery, and operation will not be interrupted.
After prolonged operation from the battery, it should be disconnected from the repeater and recharged
separately before re-connecting, as the trickle charge is not sufficient for recharging a completely
discharged battery.
Never reapply AC power to the repeater with a discharged battery connected, as the DC startup
current can damage the repeater and battery.
While operating from a battery or DC supply, the repeater requires approximately 7 amperes at 12
Volts during transmit.
Equipment Location
While the operating temperature range of the repeater is quite broad, the best location is one in which
the air temperature does not approach the extremes of the specified range, and one that does not
change rapidly. Make sure to allow for free airflow around the heatsink on the rear apron at all times.
In warm climates, the repeater should not be sealed in a small closed room.
Protect the repeater from wind and rain, and extremes in temperature or humidity that may shorten
the useful life of the equipment. Try to locate the repeater in an environment that is also comfortable
for service personnel, if possible.
Changing Switching Regulator unit AC Mains Jumper Wiring
Before attempting this jumper wire change, remove the AC power cord from the AC jack on the rear
panel.
*Referring to Figure 1, remove the 14 screws affixing the top and bottom covers of the repeater, and
remove the covers.
*Remove the eight screws affixing the shield cover for the FILTER Unit, and remove the cover (see
Figure 1).
*Disconnect all wires and connectors from the FILTER Unit, then remove the six screws affixing the
Switching Regulator Unit, and remove it (the Switching Regulator Unit is mounted with the FILTER
Unit: Figure 2).
*Referring to Figure 3, remove the four screws and remove the heatsink from the Switching Regulator
Unit.
*Referring to Figure 4, perform the correct jumper wiring on the Switching Regulator Unit for the AC
Mains voltage used in your area (100-127 VAC or 207-253 VAC).
*Replace the heatsink onto the Switching Regulator Unit, then replace the Switching Regulator Unit
onto the chassis, and connect all wires and connectors to the FILTER Unit.
*Replace the AC fuse (FH6001) on the FILTER Unit according to the AC Mains voltage range:
100 VAC (100-127 VAC): 5A
200 VAC (207-253 VAC): 3A.
*Replace the shield cover and replace the top and bottom covers. This completes the wiring change.
Important! : If you change the AC voltage range, you must also change the AC fuse on the FILTER
Unit. Do not replace with a slow-blow type fuse.
CE-27 Programming Software Instruction
With the CE-27 Programming Software, you can quickly and easily program the Vertex VXR-7000
repeater' s channels and configuration from your personal computer. In the event of an accidental
memory failure, repeater memory and configuration data may be re-loaded in a matter of minutes.
The CE-27 Programming Software diskette contains the following files:
. CE-27.EXE
. CE-27.HLP
Before connecting the VXR-7000 for programming, turn off both the computer and the VXR-7000.
