AUTODIAL No. 109

Autodial No. 109, sales name Trent, offers the same facilities as (Tyne), plus several other benefits listed below:-

- On hook dialling with monitor loudspeaker to keep the caller informed of call progress.

- LED display showing the number called, automatically changing to a call timer once the handset is lifted and the call begins.

- 24 hour clock when the unit is not in use. Time and date.

The following are minor differences compared to Tyne:-

The MF4/LD slide switch is between the two PCB's, but is placed along the side of the unit.

To make an outgoing call, the required address memory button is pressed and the built in loudspeaker monitors the progress of the call. The telephone handset must be lifted once the called party answers. The volume of the monitor amplifier / loudspeaker is adjustable by a three position switch on the back of the unit.

ADDITIONAL INFORMATION
When originally introduced in 1983, it was considered the main use of the autodiallers would be as an attachment to PABX extensions. For this reason, the user guide in all cases refers to the autodiallers as having 18 store memories and not 20. The reason for marketing in this manner, was that after the customer has entered the PABX access digit and Pause, they then have 18 usable digits to programme into any memory store.

There is a backup battery which will keep the stored memory for about 72 hours.  The LCD dispaly will only operate with the mains transformer switched on.

A unit that displays the symptoms of sending wrong numbers and unable to program is usually caused by a faulty battery.

USER INSTRUCTIONS
TRENT

To Set the Time and Date:-

1. Press STO button twice, and keep pressed the second time. This will display an empty screen for a new unit, or the time and date that requires alteration.
2. Using the numbered buttons set the time and time. Digits appear on display as you key them in. Use 24 hour clock i.e. HH. MM. DD. MM. YY.
3. The clock will continue when you release the STO button.
4. If you make a mistake, press the CAN button and release STO. Start again from step one.

Storing a number:-

1. Press and hold down the button marked STO. A row of dots appears on display.
2. Press and release the selected address button. Any one of the 50. The dots on screen blink once.
3. Use the numbered buttons (right side) to input the desired number. Up to 18 digits. The programmed digits will appear on the display as they are keyed in. When connected to a PABX that requires a Pause after the Access Digit, Press button 'A' once.
4. Release the STO button when the number is stored and write the name or telephone number on panel adjacent to button.

Note:- That unless Trent is set for MF4 signalling by an engineer at installation, the * and # buttons have no function. There is no soft switching from LD to MF4 by pressing the * button as with most modern equipment.

To call a stored number:-

1. With the telephone handset on its rest, select the desired address button and press it once. You will hear Dial Tone via the loudspeaker monitor and as the dialling progresses, the digits will appear on the display as they are dialled. The volume of the monitor can be adjusted by the three position switch at the rear of the unit.
2. When the call is answered, lift the telephone handset to speak. The display will then show a count of seconds and minutes until the call is terminated. The display will then revert to the time and date.

If at any time before the handset is lifted you wish to cancel the call, press the CAN button, this will release the call.

Should you wish to switch back to the monitor during a call, press and keep pressed the MON button until the telephone handset is replaced. You can switch between the monitor speaker and handset as often as you like during a call, including incoming calls or calls dialled from the telephone.

Certain types of PABX do not signal the public exchange dial tone, e.g. Monarch 120. In this case when storing numbers, do not programme a pause after the access digit. The continue (CON) button, if pressed will allow the callmaker to continue dialling in the absence of continuous dial tone.

Reprogramming:-
Reprogramming an address store automatically over writes the previous number. To clear a store, press and keep pressed the STO button, select and press the required address button then release the STO button.

LJU 10/7A cord connections for all autodials is as follows:-
