1. ABOUT THE 7900 PAGER
About
Commtech‟s 7900 Pager is as clever as it is simple. Designed for alphanumeric, numeric
and tone only paging applications, it‟s a dream come true.
Reliability
Reliability is one of the key factors when considering a pager. Not only does this
determine how reliably the pager receives the message but it also determines the expected
life span of the pager. That‟s why the 7900 is backed by a full 12 month warranty and is
available in over 30 countries across the globe. Coupled with this, all repairs and
warranty claims are conducted locally, by Commtech.
Ease of Use
Plain and simple. That was the specification for the design of the „user interface‟. An
intuitive menu system guides the user through the pagers functions with ease. The display
characters on the 7900 extra large, making it easy to read when you are in a hurry.
Features
The 7900 will run rings around other pagers. Boasting simple delete, delete all and
message reading facilities. It‟s also possible to change alert melodies, vibration and even
set up to 5 daily alarms if you wish. The 7900 also comes with an easy to use telephone
book that allows you to store up to 20 names and phone numbers. One of the unsung
features of the 7900 is the low purchase price, and the low cost for spare parts. Commtech
has ensured that the 7900 meets many requirements, including capital budgets!
Synthesized
Do you have multiple frequencies and require one pager to solve all your problems? The
Commtech 7900 will help. The 7900 is a fully synthesized pager, simply program in the
frequency you require and hey presto, you‟re done. This translates to less stock and much
faster supply times.
