6. Joining Units
All INDeX DT phones and TT phones can use a pair of wall brackets for
wall mounting. The brackets can also raise the angle of phones on the
desktop and can be used on DSS/BLF units.
In addition a terminal link bracket is available. This allows you to link the
wall brackets on two units, eg. to link a DSS/BLF with a DT/TT phone or
to link two DSS/BLF’s together. Contact your INDeX maintainer for
details on obtaining these items.
7. Testing the Keys & Lamps
The DSS/BLF has a test cycle that checks all its lamps and keys. You
can do this without affecting the unit's programming (ie. your phone and
DSS key settings).
To test the keys and lamps:
1. Turn the DSS/BLF's power supply off.
2. Whilst holding down the bottom-left DSS key, switch the power
supply back on. Then release the DSS key.
3. All the key lamps should come on green and you should hear a tone.
Then all the key lamps should switch to red and again you should
hear a tone.
4. Only the top-left three DSS keys should now be on with green lamps.
5. Pressing the top-left DSS key again should now illuminate all the red
lamps.
6. Pressing the top-left DSS key should illuminate all the green lamps.
7. Pressing the top-left DSS key yet again should switch all the lamps
off.
8. Pressing any DSS key now will switch its lamp on/off in a red/green
cycle.
9. To end the test, simultaneously press any two DSS keys in different
columns.
