Thank you for purchasing the TRX-200 all modes wide band monitoring
receiver.
Please read this operating manual carefully to avoid miss operation of the
receiver. The TRX-200 is carefully designed but like all receivers the radio
can suffer from a degree of self-oscillation known as ‘birdies’. These are
from the nature of super heterodyne circuit and do not represent a fault.
NOTE: Where the text is described in [SQUARE BRACKETS][SQUARE BRACKETS]
[SQUARE BRACKETS][SQUARE BRACKETS]
[SQUARE BRACKETS] the keys
are to be pressed exactly as shown.
For example: [8] [0] [0] [ENT][8] [0] [0] [ENT]
[8] [0] [0] [ENT][8] [0] [0] [ENT]
[8] [0] [0] [ENT]
This means press the numeric key 8, followed by the 0, key followed by the
0 key, followed by the [ENT][ENT]
[ENT][ENT]
[ENT] key.
The arrow keys to the lower left of the keypad are referred to as [UP][UP]

numeric keypads. This key should be momentarily pressed only before an-
other numeric key is pressed. Do not hold the key in while pressing other
keys.

To turn on TRX-200, press and hold the [PWR][PWR]
[PWR][PWR]
[PWR] key for more than 2.0 sec-
ond and you see starting message which can be edited to the way you like.
Similarly to turn the radio off, press and hold the power key for more than
2 second.
Power requirement: TRX-200 can be operated from either three AA
size Ni-Cad. batteries, three AA size dry cell bat-
teries or external DC supply of 9 to 14V DC, 300mA
minimum.
Always use the supplied charger or regulated DC
power supply of 9 to 14VDC, 300mA or by using the provided DC connect-
ing lead. The DC input socket is 1.3mm centre positive.

Very carefully note the polarity of the battery cells. Also never attempt to
charge the receiver or connect to an external power source when dry bat-
teries are installed.Always remove dry batteries when they have run down.
Do not leave batteries in the battery compartment when the TRX-200 is
not being used for a long period of time, remove the batteries to avoid
leakage.
All memory channel data is stored into internal EEPROM which does not
require batteries or connection to external supply for backup. However
always turn off the TRX-200 whenever radio is not in use. Particularly
turn it off while charging.

up and down in the selected frequency increment and also operates as
a “selector” when entering certain data through the LCD menus. Being a
mechanical data device, it is not uncommon for operations to be
occasionally missed and this does not represent a fault.

Earphone socket/RS232C serial port: This 3.5mm stereo socket permits
connection to an external earphone, headset or speaker of 8 ohm
impedance or greater. When the earphone socket is used, the internal
speaker will automatically be muted. This can also be used as RS232C
serial data port, making the TRX-200 capable of being connected to the
RS232C serial port of a personal computer.
