TX71 USER GUIDE
INTRODUCTION
The TX71 provides the only method to disarm your
security device (SRI-G or SRI-MG). The remote control
uses pseudo-random encryption to alter the
transmission code each time the a disarm signal is sent.
This patented technology ensures would-be thieves
cannot record your code and play it back to the security
device installed in your car.
PHYSICAL DESCRIPTION
bottom half of the remote case. Both batteries will face
with positive side down.
Always remove both old batteries and discard in an
appropriate manner. Insert the new batteries and reassemble the case in the reverse order to
disassembling.
NB: When snapping the case halves together, ensure
the silicon membrane alignment is correct. Failure to
do so may pinch the membrane and allow water to
enter the remote control.
CASE TOP
The TX71 is a black ABS plastic formed in two halves.
The maximum case dimensions are 54mm x 32mm x
12mm
The two halves are friction snapped together. Between
the two halves is a silicon membrane which provides
water ingress protection. The membrane is also
designed to support and protect the printed circuit
board.
The case also include a large key ring loop to
conveniently attach the remote to the driver’s keys.

CASE COLOUR BLACK
BATTERY POWER SUPPLY
The remote circuitry is powered by two CR2016 3 Volt
Lithium batteries placed one on top the other,
supplying 6volts.
BATTERY REPLACEMENT
When the battery is low the effective range of the
remote control will decrease. This can be temporarily
overcome by moving closer to the vehicle. However,
replacement CR2016 batteries should be purchased
and exchanged with the current batteries.
To replace the batteries, use a small flat blade
screwdriver to lever between the two halves of the
remote case. Disassemble the entire remote control
paying particular attention to the order in which the
pieces come apart.
The batteries will remain locked in place within the
