There is a second type of remote control supplied

with your "pro-alpha" garage door operator, viz.

the "Wall-Mounted Push-Button". This console

has a three function control, viz.:-

1) to control the door operator, and

2) to switch on the operator's own

courtesy light.

3) to enable the "lock-out" feature.

COURTESY LIGHT:-

The powerful courtesy light may be switched "ON"

without first having to activate the door.

This is very handy especially when walking into a

darkened garage. The light will stay on for 3-4

minutes

6.7 THE WALL-MOUNTED

PUSH-BUTTON CONSOLE

The best place to keep the Transmitter is in

your car. Use some “VELCRO” tape to stick

the TX to the back of your car's sunvisor. ( Fig

17 )

Your TX will always be at hand; no possibility of

misplacing it ; it will not be subjected to abuse

and, what's more, it will afford the radio

equipment the most favourable placement to

ensure a good working range.

6.4 CHANGING THE TX BATTERY

TO CHANGE THE TX BATTERY:-

Remove the cover of the Transmitter.

Carefully insert the new battery making sure that

the "polarity" of the battery, ( i.e. positive and

negative ends of the battery ), is correct. Both the

battery and the Transmitter Casing are marked

with + and signs.

Take care not to disturb the positions of the

Dip-Switches as this will change the Signal

Code thus causing the radio controls to

malfunction and consequently the door

operator will not work.

The Dip-Switch settings of the Receiver and

Transmitter must match each other!!!

TAKE NOTE .....

The parameters for coding Multi-Button

Transmitters such as 2, 3, & 4 button types are

different to those for the 1 button types.

See section 6.9 "CHANGING THE RADIO

CODES".

The Radio Receiver is connected to the Control

Board of the door operator, and is normally placed

inside of, or in close proximity to the operator.

The placement of the receiver isvery important as

the "range" at which the radio equipment will work is

largely dependent upon the receiver having an

unobstructed reception path, i.e. the aerial

must not be shielded inside a metal casing, nor

should the RX be fixed to metal pipes etc., etc.

See section 6.6 "RADIO PERFORMANCE”.

6.6 RADIO PERFORMANCE

The effective transmitting range of standard low-

power radio remote control equipment is of the

order of 15 - 20 metres..... measured in direct

"Line-of-Sight" from the Receiver Set.

So called "long range" radio controls which have

an effective range of 50 - plus metres are also

available on request.

The transmitting range is greatly influenced by the

surroundings and garage structures as well as the

approaches to the garage.

For example:-

Concrete ceilings, corrugated steel roofs and

steel doors will reduce the effective range of the

radio transmission!

Trees and bushes close to the garage will also

adversely affect the transmitting range!

Basement garages will also restrict the range!

Weak batteries will reduce the transmitting range

to zero!

Transmitters which are surrounded by a bunch of

keys will not give of their best performance.

The placement of the radio receiver and the

position from which the transmitter is operated

has great influence on the performance of the

equipment.
