Dial Click Card
On newer Dual Dial Click cards (rev. C and later), you can usually avoid the following
adjustment procedure. Instead, turn both pots up (clockwise) to maximum. This usually
gives good results. If not, back down until you attain reliable operation.
This procedure applies only if the Dial Click Option for the 702-9037 card or the Dual
Dial Click Option for 702-9117 card is installed. For this adjustment, you will need the
following test equipment:
• Extender card (702-9087)
• Touch-tone telephone
• Rotary dial telephone
• Phone cord “Y” connector for your two telephones
This level adjustment is only affected by the adjustment pots on the dial click card. The
“FROM TEL” pot on the telephone trunk card has no effect.
To make your adjustments, you will need access to the pots on the dial click card. So,
power-down the Model 2100/2200 and place the trunk card you wish to adjust on the
Extender Card and re-power the unit. Connect your two telephones together with the “Y”
connector into the same telephone wall jack.
After the terminal completes booting up (about two minutes), call into the paging terminal
and access a tone & voice pager that you have programmed with lots of voice time (e.g. 60
seconds). During the voice recording time, pickup the rotary telephone and hang up the
