4. Rechorgingqnd A-Coperotion
CORNETOK is built only for A-C currentor
bottery operotion. Before plugging in, turn
switch-ringto left ond flop opens outomqti-
colly. Inserto shorp pointed obiect into the
opening(l ) ond odiustvoltoge by slidingup
or down os required(220or I l0/l 25Y Io I l0).
Dqnger! The CORNETOK moy not be used
on D-C current!Use only stondqrdUltrqblitz
moins coble os listed on poge 16 os qcces-
sory.
To swilch unil, connect moins coble with cr
normol householdelectricsocket.When this
hos been done, the octuol chorgingof the
bottery b"gins. Thot's oll    nothing else is
necesscrry.The red signollightsup ond shows
you thqt the bottery is being chorged.At the
sqmetime,you con flosh os often os you like
-  this will not dischorgethe bottery.
To lurn off, iust pull plug out of electricsocket.

The built-in bottery is seqled oir-tight ond
requiresno servicing.Thesequenceof flqshes
tells you whether the bottery is fully chqrged
or not. The flqsh sequenceis defined os the
time intervql which elopses between flosh
ond lightingup of red signo| :


opprox. l0 sec -  fully chqrged
opprox. l8 Sec_ hqlf dischorged
opprox. 30 sec - completelydischorged


At the very lotest,bqttery should be rechqrg-
ed when flqsh intervol is down to 30 se-
conds. ln this cqse, o  f u ll chorge will toke
obout 14 hrs. The bottery is not domoged,
however, if  it  is left unchorged for longer
periods of time.

An occosionoloverchorgeis not domoging.The bottery hos on exceptionolly
long life of obout 400 to 500 rechorges. lf by mistoke the mechqnism is left
turned on for o long period of time, the bottery will dischorgeqnd vibrqtor

5. Reformingthe StorogeCondense

When flosh hos not been used for severc, weeks, it is best to plug  it in on
eleetricsocket for20 to 30 minutes.This will reform the electrolytecondenser
