2.1.3 USER CONFIGURATION
The RPT700 does not provide the ability for a user to make changes to the radio frequency, the
radio bandpass, change the mode of operation, changes to the maximum R.F. power, or being
able to modify the repeater in any way that will affect the designed and certified operation.
Prevention control is managed by the use of factory preset cavity filters, maximum RF transmit
power is digitally controlled and factory calibrated only. Any such changes are only able to be
made by the factory.
The only user controlled variable is the ability to manually change the RF gain via the external
toggle switches. Maximum RF Power is digitally controlled to a maximum of one Watt. The
digital control will not allow an increase of RF Power over one Watt irrespective of the user
adjustments.
The RPT700 contains no user replaceable parts and requires no additional calibration once
installed.
2.1.4 AC POWER DISTRIBUTION
AC input power is through a power cord then a 2-pole on/off circuit breaker switch which feeds two DIN
rail mounted fuse holders with cartridge fuses rated at 5 AMP and 5 AMPS. The fuses are replaceable and
each DIN rail fuse holder holds a spare fuse. AC power from the DIN rail fuse holders feed two DIN rail
switching power supply units. The power supply units are adjustable to operate on either 220 VAC or
240VAC. (Customer to notify Telcosat Inc with AC power requirement prior to shipping)
The internal power supply units convert AC line voltage to DC power, one power supply unit supplies
10volts DC and the other power supply unit provides 28volts DC. The DC power provides all the
necessary requirements for the active components.
