Postpone the SB6121 cable modem installation until there is no risk of a thunderstorm or lightning activity in the area.
To avoid damaging the cable modem with static electricity:
-
Always first connect the coaxial cable to the grounded cable TV wall outlet.
- Before connecting or disconnecting the Ethernet cable from the cable modem or PC, always touch the coaxial cable connector on the cable modem to release any static charges.
To avoid potential shock, always unplug the power cord from the wall outlet or other power source before disconnecting it from the SB6121 rear panel.
To prevent overheating the SB6121, do not block the ventilation holes on the sides of the unit. Do not open the unit.
The product is capable of operating in an ambient temperature range of 0?C to +40?C (32?F to 104?F).
Wipe the cable modem with a clean, dry cloth. Never use cleaning fluid or similar chemicals. Do not spray cleaners directly on the unit or use forced air to remove dust.
