3. Rechorgingcnd A-Coperation




MO N O J ET is built only for A-C
current or bottery operotion.Before
plugging in, turn switch-ringto left

opening (1) ond odiust voltoge by

To switch unit, connectA-C coble with q nor-

At the very lotest,bottery should be rechorgedwhen flosh intervol is
down to 30 seconds.In this cqse,q full chorge will toke obout l4 hrs.
The bqttery is not domoged, however, if it is left unchorgedfor lon-

4. Reformingthe StorogeCondenser
When flqsh hos not been used for severqlweeks,it is besf to plug it
in on electricsocketfor 20 to 30 minutes.This will reform the electro-
lyte condenserond the unit will reqch its full flqsh power ogoin.

5. Automotictronsistorizedmonitoringcircuit




The trqnsistor-reloy-circuitof the MONO  J ET sovesthe bottery
ond outomoticollykeeps light output constont.When moking
pictures it is not necessoryto turn off the unit to sove bottery.
Just os soon os the MONO JET hos been turnedon, theouto-

Whenever doylightor constontsourcesof ortificiollightore ovoiloble,
correct exposure is reguloted by meqns of shutterspeed ond stop.
However, if the very short electronicflosh is used,correct exposure
con only be reguloted by the diophrogm stop. The stop computor
offers on eosy woy of oscertoiningcorrectstop. lf you ore using block
ond white film, set block orrow qt vqlue correspondingto sensitivity
of fifm used (for exqmple: ASA 25),use red qrrow for colorfilm. Pro-
