Problem: Our operators live in an area which has a dial pulse ex

change. How can they acknowledge the B1290 when it calls?
- Even though the operators have rotary phones, they can still send tone
codes if they have a DTMF pad, purchased separately, which sits by the
phone.
- The B1290 may be programmed to automatically acknowledge after eight
rings. ThusiftheB1290callsanoperator witha dial pulsephone, the opera

tor can hang up after he hears the message, call the B1290 right back, let the
phone ring eight times, and the B1290 will recognize that as an acknowl

tion section (Program Code 4), and put a Wait command in the next
directory line to allow time for them to call the B1290 back.
Problem: How can I prevent unauthorized personnel from calling up
the B1290 and altering its programming?
- In its default condition, the B1290 does not require any type of password.
If you wish to enter one, refer to the Access Code in the DTMF Codes sec-
tion (Program Code 3). If an Access Code is programmed, anyone calling
the B1290 will receive a report of its status, but it will prompt the caller to
entertheAccessCode beforeallowingthemintotheprogrammingmode.
Problem: Can I use the Þ character as part of my DTMF strings?
Won’t this be confused with the “Enter” code?
-The# andÞ charactersmaybeused as apart ofany programmable DTMF
string. The only time you must be careful is when entering an asterisk (Þ)
asthe lastdigit in astring. Besure towait morethanone secondafter enter-
ing the last digit before hitting Enter (ÞÞ); otherwise the last Þ will be in-
terpreted as part of the Enter code.
Problem: The B1290 has lost its programming.
- As it runs, the B1290 is constantly performing internal self-checks, and on
rare occasions it may find that a memory location has been corrupted. If
that happens, the B1290 resets all programmed parameters (except the
voice messages) to the default values. At the same time, it will announce
Program Code Error over the radio. As the telephone directories have been
lost,the B1290 cannotdial out toreportthe failureoverthe phone. Theonly
way you will be able to tell that something has gone wrong is by phoning
the B1290; it will announce a Program Code Error as soon as it answers the
phone. In order to have some local indication that an error has occurred,
hook a local speaker into the radio connections.
The most common causes of a memory loss are power spikes which enter
