General Precautions
Minimise handling of static sensitive modules and components.
Wear a grounded anti static wrist strap while handling static
sensitive components.

Do not bend or stress the modem in any way.
Reinsert connectors straight and evenly to avoid causing short
and open circuits.
and open circuits.
ESD Handling Precautions
The Boomer-III OEM modem contains components sensitive to ESD
(electrostatic discharge). For example, people experience up to 35kV
ESD, typically while walking on a carpet in low humidity
environments. In the same manner, many electronic components can be
damaged by less than 1000 volts of ESD. Although the Boomer-III
modem has been designed with a high level of ESD protection you
should observe the following handling precautions when servicing
host/terminal devices:

Use a static safeguarded workstation, which can be set up by
using an anti static kit. This kit typically includes a wrist strap,
two ground cords, a static control table mat, and a static control

When anti static facilities are unavailable use the following techniques
to minimize the chance of damaging the equipment:
