Insulated and Moisture-Protected Telephone Set
Sets for Bathrooms

It is known that contact between the relatively moist human body and a live electrical object, even if the voltage is low, can cause a shock or temporary discomfort; this is particularly common among people who use the telephone while in the bath or have just gotten out of it.

It is therefore important to avoid using electrical devices that could cause such shocks, either due to insufficient insulation or any other accidental fault.

In the case of a subscriber telephone set, the fault could be, for example, accidental contact between one of the line wires and the metal casing, or any similar malfunction.

These considerations led us to present a telephone set specially designed and protected from damp to withstand, without damage, a hot, humid atmosphere, such as that found in bathrooms.

Tabletop Telephone No. 2845A
The brass plate forming the base of this set is covered externally with a phenolic fiber sheet, and the mounting screws are made of insulating material.

The perforated operating disc and the stop for the finger on the dial are made of Bakelite, while the numbered disc is made of a transparent insulating material called "Diakon."

The connecting cords are of the fully rubber-covered type.

The capacitors, induction coils, and ringer have been specially finished to effectively withstand the humidity of bathrooms.

All exterior parts of the Telephone No. 2845 have a white finish, giving them a pleasing appearance.

However, other colors are available upon request.

Note that this station operates with the same safety features as our Standard Telephone, the No. 2724.

Wall-Mounted Telephone No. 2846A
This wall-mounted station is identical in all respects to the table-top station in terms of protection.

However, the base plate is not insulated, as it is inaccessible due to the station's wall-mounted location.

Note that this station operates with the same safety features as our Standard Telephone, the No. 2725.
