■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
LIMITATION APPLICABLE TO M-RESTER
The M-RESTER will protect electronics equipment from
damage caused by lightning by absorbing most of the
surge voltages.
However, M-RESTER may not be effective against cer-
tain extremely high voltages caused by a direct or almost
direct hit by lightning.
M-RESTER must be installed according to this installa-
tion / instruction manual.
GENERAL
■ FUNCTION & FEATURES
• Designed specifically to protect telecommunication equip-
ment from lightning surges entering through telecommu-
nication line network
• Easy connection to the protected equipment with modu-
lar jacks
• Connection with a telephone and a modem in parallel
• No interruption of transmission signal by unplugging the
protector element

POINTS OF CAUTION
■ ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the surge protector inside proper housing with
sufficient ventilation.
• Do not install the surge protector where it is subjected to
continuous vibration. Do not subject the unit to physical
impact.
• Environmental temperature must be within -5 to +55°C
(23 to 131°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■ DIELECTRIC STRENGTH TEST
• Loosen the screw located at the left-center of the element
and remove the element module from the base before
conducting a dielectric strength testing. Otherwise the
element will start discharging at a voltage exceeding the
max. continuous operating voltage (Uc), which can cause
insulation failure of the module.
Be sure to return the element and fasten securely after
the test.
■ AND ....
• We recommend that you keep spare surge protectors so
that you can replace them when necessary.
• Lightning surge can enter not only through signal lines
but also through power supply lines. We recommend that
you also use the surge protectors for power line for suffi-
cient protection.
