Using the supplied wall mounting pattern for correct positioning, drive two wood screws
or anchor bolts into the wall surface to a head height of less than 0.3" (8mm). Then insert
two fixing holes on the speaker's rear cover onto the screws or anchor bolts for mounting.
(The pattern is printed on a flap of the carton box containing this speaker.)

Precaution
The speaker weighs
3.5 Ibs (1.6 kg). When there is a
danger that the speaker falls,
reinforce the wall strength with
anchor bolts, etc.
The F-5 is factory-preset to 10 watts (490 ohms). Follow the instructions below to change
the wattage.
Remove four screws on the rear and detach a baffle board from an enclosure.
Change the connection of a red input lead from the prewired tap to that of desired im-
pedance (wattage). In this event, tighten the connection.

For low impedance applications, remove a red lead and a black lead
connecting between the matching transformer and speaker unit. Then
connect both leads from the input terminal directly to the speaker unit.
(Connect the red lead to " + " terminal of the speaker unit.)
