MOUNTING THE MODEM

The modem contains static-sensitive devices and

should only be handled by personnel and in areas that

are properly protected against static discharge.

There are two mounting techniques that are

recommended for physically connecting the modem to

your circuit card; 1) sockets, and 2) direct soldering.

The socking approach to mounting eliminates cleaning

and desoldering concerns. When the socket is used, it

must make a solid connection to all modem pins.

Failure to do so will cause unreliable modem operation.

Also, steps should be taken to assure that the module

remains tightly seated in the socket after the host

product is shipped.
