Systems 9000 accessories

Hang-up boxes:
When the Syntor X microphone is in the hang-up box, the switch is closed and the receive PL/DPL decoding is enabled. When the microphone is removed, the switch opens and the receive PL/DPL decoding is disabled. The PL/DPL disable switch opens the circuit to disable the receive PL/DPL decoding, regardless of where the microphone is. Be careful, not all hang-up boxes work this way. All of these PL/DPL hang-up boxes should work with the Syntor X:
HLN4024A - Hang-up Box (Mitrek)
HLN4025A - Hang-up Box with PL/DPL Disable Switch (Mitrek, Motrek)
HLN4188A - Hang-up Box with PL/DPL Disable Switch (Syntor, Syntor X 800 MHz, Syntor X)
HLN4830A - Hang-up Box with PL/DPL Disable Switch for HHCH (Syntor X)

Handset hang-up cradles:
The handset hang-up cradle is only slightly more complicated than the hang-up box. The cradle is used with the telephone type handsets. Different cradles can switch the receive audio to a speaker (Audio Switching), control the PL/DPL decoding disable with a switch or automatically disable PL/DPL decoding when the handset is removed from the cradle (Automatic Monitor):
