flash symbol  . This is equal to about 1/40 sec., the shortest possible exposure speed
to be employed with electronic flash. 

Insert flash cable into the flash socket (17) marked "X". 

Regarding aperture settings you will find directions, in form of so-called "guide
numbers", given on the wrappings or in the literature coming with the bulbs and
electronic flash units. The aperture of the lens and the distance between flash unit and
subject are brought into balance on base of these guide numbers. 

To find the correct aperture, divide the guide number for the flash in use by the flash-to-subject distance figure.

P) Exchanging the power source

Power source for the automatic exposure system is a Mallory Mercury Oxide Battery PX 625, PX 13, or a similar type,
having a nominal voltage of 1.35 V. 

Owing to the low consumption of current and the short working period of meter reading, the battery lasts about 2 years.
To exchange batteries, screw out the cover (22) in the bottom of the camera with the aid of a coin. Insert new battery,
making sure that the "+" sing is visible. Replace cover (22) and screw it tight. 

Attention: Do not load the discarded battery or throw it into the fire. Both may cause an explosion!

Q) Maintenance of camera and lens

Perfect functioning and lasting service of your PRAKTICA super TL depend very largely on careful maintenance and proper
handling of the camera.
The PRAKTICA super TL is a highly valuable precision instrument. It must, therefore, be protected against shock and dust.
(Use everready case).
Never use force when operating the mechanism.
From time to time dust and film emulsion deposits have to be removed with a soft brush from cartridge chamber, spool
chamber and film track. Do not touch the optical parts (lens, eyepiece of viewfinder, and mirror) with your fingers.
Should you have done so accidentally, any fingerprints must be removed immediately with a soft brush or a piece of fine
linen.

R) Accessories

Many interesting results in picture composition are obtainable with the aid of accessories.
