Teledex B-Series - Manual (Page 83)

Your B450D telephone has been designed to give years of trouble-free service.
It is a sensitive electro-mechanical instrument. To assure its longevity, please
read the following maintenance instructions:
1. Keep the B450D away from heat as high temperatures can shorten the life
of the electrical components and distort or melt its plastic parts.
2. The B450D should be kept free of dust and moisture. If it gets wet, wipe it
dry immediately. Liquids can contain minerals that can corrode electronic
circuits.
3. Handle your B450D gently and carefully. Dropping it can cause serious
damage to circuitry or the plastic case, which may result in malfunctions.
4. Do not use any type of chemical or any abrasive powder to clean the outer
casing. Use only mild detergents on a soft, damp cloth to clean the B450D
telephone.
5. The B450D has built-in surge protection circuits that meet or exceed FCC
requirements. However, an incident such as a lightning strike at or near the
telephone lines, could cause serious damage.
6. If the B450D is installed in an area with frequent or severe electrical
storms, it is suggested that the telephone be disconnected during these
storms or that additional surge suppression equipment be added to the
installation.
7. In the case of trouble with the telephone, do not attempt to repair the
telephone yourself. It is the responsibility of users requiring service to
report the need for service to our Service Department. They will make the
necessary arrangements for repair or replacement.

Message Waiting
Based on the priority settings that you have selected (see “Telephone Setup”
starting on page 15), the phone will receive VMI (or visual message indication)
for one or none of the four lines.
If you subscribe to voice mail from the telephone
company and if there are voice mail messages that
have been left in the voice mailbox on the priority
line, the display will show “MESSAGE WAITING.”
Note: This function requires voice mail subscription
from the local telephone company. Furthermore, the local phone
company must provide a type of voice mail signaling called “FSK”
(Frequency Shift Key). Not all telephone companies have the visual
message waiting feature (or the deactivate signal) available. Please
contact your local telephone company to check if this is available in
your area.
If it is necessary to manually cancel VMI indication:
1. While “MESSAGE WAITING” is on the display, press [ DEL].
2. The B450D will display “CANCEL MSG WAIT?”
3. Press [DEL] to confirm, or [QUIT] to quit without cancelling VMI indication.
4. After [DEL] is pressed, the display will show “MSG WAIT CLEARED” and
return to the idle mode.
