Simrad RS8400 VHF Radiotelephone
The VHF system is designed for remote installation of the main unit. Operation is carried out through the waterproof handset, which can be installed up to 20 m (65ft) from the main unit. Information regarding channel selection, operating mode and output power is always given on the handset display. Volume and Squelch levels are displayed momentarily when settings are changed. Selection of an unauthorised channel is indicated by the legend ERROR. The keypad has numerical keys for channel selection and function keys for controlling volume, squelch and scan modes. Key P (WX) allows access to private, authorised channels. In addition, key E allows access to secondary functions. The legend SHIFT will be shown in the handset display whenever this key is pressed. All key entries are acknowledged by short tone in the loudspeaker.
