FAQ
1.
What if the spammer presses 0 after hearing the warning?
It almost never happens in reality, as long as your warning message doesn't sound too inviting. If it does happen, find it
in the White List, press and hold REJECT to move it to Black List.
What if I don't want to hear the single phone ring from blocked calls?
2.
You can press and hold RINGER until ALLOW 1 RING shows, press again to change to ALLOW 0 RING, then DEL/EXIT to
save. Please note that certain telephone sets will not show caller ID when ALLOW 0 RING is on.
What if I wait for a call that is not on White List, like delivery, pharmacy, etc?
3.
You can turn SENTRY off temporarily by ON/OFF button. When SENTRY is OFF, it allows all calls to come through,
except Black List callers. Afterwards please don't forget to turn SENTRY back on.
4.
Do I need to add "1" to phone numbers when creating the White List?
Please check the caller IDs showing on your home phone. If you see CID displaying as "1+10 digit" on your phone,
then you need to add "1" in front of area code.
5. Frozen up? Disconnet phone cables and remove batteries can reset the unit.
6. How many messages can SENTRY save? Two, the older message will be automatically saved over.
