Model LFH0085
General Description: The LFHoo85 "Pocket Memo"
is a miniaturised,
battery operated, cassette loaded, dictation machine.
It is completely self
contained; the battery, micro-cassette and combined microphone/loudspeaker
all being housed within the pocket sized casing. A socket is provided for the
use of stethoscope headphones, if desired in lieu of the internal loudspeaker.
Provision is also made for the re-recording of recorded matter on to a Philips
EL3581, EL3582 or LFHoo84 dictation machine by means of an inter-con-
necting dubbing (copying) lead.
Battery: gvolt (PP3 or equivalent), at 35mA approx.
Battery Check: The battery should be checked periodically to see if it still
provides sufficient voltage. To do this, depress the top of the side rocker
switch and press the battery check control (above volume control). If an
audible tone is heard from the loudspeaker the battery is still good.
