AFX-150  (430-1240)          Care and Maintenance     Faxback Doc. # 14118

Your Fax Switch is an example of superior design and craftsmanship. The
following suggestions will help you care for the Fax Switch so that you
can enjoy it for years.

    Keep the Fax Switch dry.  If it does get wet, wipe it dry
    immediately.  Liquids can contain minerals that can corrode the
    electronic circuits.

    Handle it gently and carefully.  Dropping it can damage circuitry and
    cases and can cause the product to work improperly.

    Use and store the Fax Switch only in normal temperature environments.
    High temperature can shorten the life of electronic devices and
    distort or melt plastic parts.

    Keep the Fax Switch away from dust and dirt, which can cause
    premature wear of parts.

    Wipe the Fax Switch with a dampened cloth occasionally to keep it
    looking new.  Do not use harsh chemicals, cleaning solvents, or
    strong detergents to clean the Fax Switch

Modifying or tampering with the Fax Switch's internal components can cause
a malfunction and might invalidate its warranty.  If your Fax Switch is
not performing as it should, take it to your local Radio Shack store.  Our
personnel can assist you and arrange for service if needed.  If the
trouble is harming the telephone lines, the telephone company might ask
you to disconnect your fax switch until you have resolved the problem.

IF YOU HAVE PROBLEMS

If your fax switch does not work or works poorly, check the connection to
the telephone line.  If the reception is noisy when you make a call, hang
up the phone's handset.  Then, pick up the handset and redial the number.

If a power failure occurs while your fax machine operates, the fax switch
might not reset properly when power is restored.  If this happens, simply
unplug the fax switch and then plug it back in to reset the switch.

If the fax switch does not transfer calls to your machine, the phone line
voltage might be too low.  Normal phone line voltage is 48 volts DC.  Your
fax switch operates with voltages down to about 35 volts DC.  If the phone
line's voltage is below 35 volts DC, your fax switch might not operate
properly.  Check with your phone company if you think you have this
problem.

LIGHTNING

Your fax switch has built-in protection circuits to reduce the risk of
damage from surges in telephone and power line current.  These protection
circuits meet or exceed FCC requirements.  However, lightning striking the
telephone or power lines can damage your fax switch.

Lightning damage is not common.  Nevertheless, if you live in an area that
has frequent electrical storms, we suggest that you unplug your fax switch
during storms to reduce the possibility of damage.
