The its correct address sequence. A continuous device includes an FX003 tone decoder tuned audio alert is generated when the decoder to CCIR, EEA or ZVEI tones and an FX103 receives its address followed by an additional address decoder. The FX1103 can operate instruction tone (tone C). Only one decoder from a three-cell battery and consumes a is required for dual address pagers. minimum of power.

Transmitted Instruction Codes: The FX1103 can decode variable (or select-on-test) capacitor. Wiring should be selectively addressed reset instructions using extra tones kept short. The frequency may be monitored at pin 14 by decoded in addition to those specified by CCIR, EEA and a high impedance counter with low capacitive loading. ZVEI.

These transmitted instructions are also valid designed to interface directly to fusable link diode under group calling instructions. . matrices. Selcall numbers are programmed into the A voice paging system organised with transmitted reset matrices directly without repeat codes (code E). The instructions offers the possibility of hands-free operation circuit automatically recognises where successive address at the receiver. digits are identical and searches for the repeat tone. The 3. Group Call: The hybrid will decode group calls where any code E is used in the memory as a terminator where less ‘one or more digits of the address have been replaced by a than five address digits are used. It is programmed into group frequency (tone A). Groups ranging from ten units the external memory after the last digit and instructs the to all the pagers on a network can be simultaneously FX1103 to search for address suffix tone codes or the no called. The hybrid will output a distinctive audio alert transmission state.
