Redial operation
After you have dialed a number, go off-line for a
moment, then press "TALK" to reconnect to the
network. Confirm that you have a dialtone, and then
press the "BIS" key on the keypad. The last number
previously dialed will be re-dialed from memory.
Redial is done in the same mode (Tone or Pulse) as
originally dialed.
You may go "off line" by pressing the R (Flash) key
or by switching from Talk to Mon and then back to
Talk.
Polarity Check
The Series 620/630 and 63FT testsets indicate
polarity continuously, without requiring a keypad
action.
To check the polarity of a line :
Connect the BLACK test lead to TIP (positive), and
connect the RED test lead to RING (negative).
Switch to "TALK" to access the network.
If the GREEN LED lights up, the line polarity is
correct; if the RED LED lights up, the line
wiring/polarity is reversed.
NOTE: All functions of the Series 6 testsets will
operate with any line polarity.
Ringer
The Series 620/630 and 63FT testsets are equipped
with an internal electronic ringer to indicate
incoming calls (Ring signals).
Connect the testset to a line. The TALK - MON
switch should be in "MON" position in order to
receive incoming calls (ring signals). The ringer
function requires a battery (except for the Series
63FT).
