An easily accessible Ni-MH battery module in each telephone provides the internal audio amplifier's operating supply and is trickle charged from the telephone line. DTMF/LD dialling and recall options The A103 is a push button telephone, purpose-designed for underground coal mining installation and use, providing automatic dialling via a surface interface into a standard PAX or PABX surface exchange. Its ruggedised, welded steel casing with stove-enamel coating is saline resistant. The telephone is made of glass filled polyester with polycarbonate curly cord handset which is impact resistant and sealed to IP55. Twin speakers give >90dBA SPL for ringing and when used as a loudspeaker unit under emergency conditions. Full 15 button keypad, plus Emergency push button operation Image for Illustration purposes only ATEX Certified Robust handset- curly cord Large tactile buttons, easy to see and operate Connection is via a simple twisted-pair cable that can be contained within a multi-core cable if required. Up to three telephones can be connected for ‘party-line’ working from one line pair by a four-core link. Operation is simple, with finger guide holes for ease of dialling, even when wearing thick gloves. An easily distinguishable button operates an emergency alert (to an Emergency desk, if fitted). The telephone may be configured for either DTMF or LD dialling. When DTMF has been selected, the Star, Hash and Recall buttons enable access to all of the extended functions of the exchange. Immediate re-dialling is achieved by use of the Recall button.
