Payphone l90MP/Payphone 190SC
The Payphone 190MP and Payphone 190SC offer you all the benefits of a payphone and all the convenience of a normal phone. They are ideal for supervised locations like restaurants and hairdressers’ salons and will sit neatly on a counter, table or shelf

Just tap in your personal identification number and you can use them as you would a normal phone, without having to put money in the coin slot.

Both these payphones have a cash box capacity of up to £25, take l0p, 20p, 50p and £1 coins and are available in grey.

The differences between the two
The Payphone 190MP (meter pulsed) charges exactly like one of BT’s public payphones and allows your customers to get through to the operator on 100.

The Payphone 190SC (self-contained) differs from the Payphone 190MP in the following ways:

It DOESN’T allow your customers to get through to the operator on 100 (although you can when you’re using it as a normal phone).

The visual display unit shows your customers the amount of credit they’ve got left in SECONDS rather than PENCE.

When the person at the other end answers, your customers have to push a Press On Answer button before they can carry on a conversation.

Although the Payphone 190SC is delivered set to the standard BT public telephone tariff of l0p for each dialled unit, you can program the time allowed upwards or downwards to influence the return you get.

Safety and space considerations
In order to reduce the possibility of your Payphone 190MP or Payphone 190SC being accidentally knocked over or stolen, it can be screwed to a counter, shelf or table-top when it is installed.

Carry on talking without a break
Your customers can carry on talking without a break whenever they have to put more money in the Payphone 190MP or Payphone 190SC.

Although coins can only be inserted one at a time, they just drop into the payphone without the need for any pressure to be applied.

Incidentally, any wholly unused coin will be automatically returned to the customer as soon as they replace the handset.

Keeping accurate records
Keeping accurate records is easy with the Payphone 190MP or Payphone 190SC.

Each model has an in-built coin trip meter which will show you the accumulated cash total (in pounds and pence) that your customers have put in the cash box since it was first installed, as well as the amount that has been put in the cash box since it was last opened (also in pounds and pence).

Going straight onto another call
If your customers have got any credit left after finishing one call, they can use it on another call by pressing the Next Call button featured on both models.

Watching over your payphone
It is not easy for people to make reverse charge calls to these payphones at your expense, or for your customers to get connected to another number for free when they shouldn’t be.

The Payphone 190MP and Payphone 190SC produce a warning tone which alerts the operator to the fact that the person answering or speaking to them is using a payphone.

However, international reverse charge calls to your payphone cannot always be prevented in this way.
The only sure way to prevent any reverse charge calls being made to your payphone is to bar incoming calls altogether, which we can arrange for you for a small charge if you ask.

Calling the world
Your customers can make local, national, international and 999 calls using this payphone. They can also speak to the operator on 100 (except when using the Payphone 190SC) and have access to BT’s Chargecard service.

Help for the hard of hearing
An inductive coupler is fitted in the earpiece of both models. It is designed solely to improve the clarity of incoming speech and reduce background noise for people wearing post aural hearing aids (which should be set to the T position). It does not affect either payphone in any other way.

Vital statistics (both models)

Dimensions 195 mm (7.68 in.) wide by 255mm (10.04 in.) deep by 160mm (6.3 in.) high.

The Payphone 190MP receives meter pulsing signals from the exchange, which means that the BT engineer will have to make a connection to the main earthing terminal on your premises. This is usually located next to the main fuse box. If you do not have a main earthing terminal, your local electricity board will install one for you (it must be in place before the BT engineer visits).
