Switch 5
his switch is used to configure a section of the CA -300DX extended memory. If dipswitch #5 is OFF this area is
assigned as the forth memory save. If dipswitch #5 is ON this area is assigned as look-up tables for [10] area
codes and [100] telephone prefix numbers. o configure the memory as look-up tables this switch must be ON
prior to initializing the CA -300DX with dipswitch #7. During an upgrade, to prevent loss of the program, perform
an erase command on the two area code and twenty prefix number table positions.
Switch 6
his switch is used to determine the type of dialing during an autopatch. If dipswitch #6 is OFF, the CA -300 will
dial with D MF tones. If dipswitch #6 is ON, the CA -300 will pulse dial at a 10 pulse per second rate. o increase
the rate to 20 pulses per second, set control channel Zone 5 Channel 7 to ON.
Switch 7
his switch is used to initialize the CA -300. Set this switch to ON. Cycle the power OFF and back ON. During
power-up, the memory will be flushed and reloaded with default values. he voice will say: "RESE DA A LOAD
COMPLE ED." Set switch #7 to the OFF position.
Switch 8
his switch is used to program a new unlock number. Set switch #8 to ON. he voice will say: "EN ER
CON ROL." After the seven-digit unlock number is entered, set switch #8 to the OFF position. Switch #8 is also
used to activate the computer interface. See chapter 14. urn the DC power off. Set switch #8 to ON and turn

Chapter 3 - Repeater Control
he CA -300 has a maximum capacity of 64 remote control channels. hese channels are segregated into eight
zones according to their function. In addition to being controlled by the scheduler, these channels can be manually
controlled by D MF commands on the repeater, or telephone inputs.
nterrogation of Repeater Control Status by Radio
Key-up and send the control operator prefix number followed by the zone number and a zero. Un-key and the
voice synthesizer will read back the channels that are turned on in that zone. Example: "ONE WO FIVE ON." If
all the channels are turned off, the voice synthesizer will say: "ALL CLEAR."
Changing Repeater Control Status by Radio
o change the status of a channel, key-up and send the control operator prefix number followed by the zone
number, channel number and a [1] to turn the channel ON or a [0] to turn the channel OFF. Un-key and the voice
will read back the zone, channel number and control activity. he voice will say: "ONE ONE ON." or " HREE FIVE
OFF." Example: With a control operator prefix of 100, turn Zone 3 Channel 5 ON.
Un-key and the voice synthesizer will say: " HREE FIVE ON."
* he momentary command is limited to Zone 6, Channels 6, 7 and 8.
Changing Repeater Control Status By Telephone
Call the repeater by telephone. When the CA -300 answers a beep will be heard. Enter the control operator prefix
code followed by a (#) pound. he voice will say: "CON ROL READY." You need only enter the Zone number,
Channel number and a (1) to turn the channel ON or a (0) to turn the channel OFF followed by the (#) pound. It is
not necessary to enter the control operator prefix number before each command when controlling by phone. o
