If you require basic functions, the Standard Model HF-90 is
quite suitable. However, if you require advanced functions
such as Selcall related facilities, then you will need the
Advanced Model HF-90. This is an additional option.
If you have a Standard Model HF-90, you can have this
upgraded to an Advanced Model easily and cost effectively.
The upgrade comprises of new operating software and a
DTMF (Dual Tone Multi Frequency) microphone or
handset. Simply enquire with your Q-MAC Representative.
Section 6 of this Guide covers functions which are available
only on the Advanced Model HF-90. All other Sections of
this Guide are relevant to both Models.
