Attaching / removing the LEICA <strong>SF</strong> <strong>58</strong><br />
Note:<br />
In general, switch off the flash unit and the camera before attaching / removing<br />
the flash unit (see next Section).<br />
1. Turn the knurled nut (1.1a) upwards all the way towards the flash unit housing.<br />
The locking pin (1.1c) is now fully retracted in the adapter foot (1.1) of<br />
the flash unit.<br />
2. Slide the flash unit with its foot all the way into the flash shoe of the camera.<br />
3. Turn the knurled nut all the way downwards against the flash shoe of the<br />
camera body and thus clamp the flash unit in place.<br />
Note:<br />
In camera bodies with flash shoes lacking a hole, the spring-loaded locking pin<br />
retracts into the foot of the flash unit to avoid damage to the surface of the<br />
flash shoe.<br />
Removal<br />
1. Turn the knurled nut (1.1a) upwards towards the flash unit housing all the<br />
way.<br />
2. Remove the flash unit from the flash shoe of the camera.<br />

Switching the LEICA <strong>SF</strong> <strong>58</strong> on and off<br />
The LEICA <strong>SF</strong> <strong>58</strong> is switched on and off with the main switch (1.17). To switch it<br />
on, the switch is pushed towards the right to the “ON”-position, to switch off,<br />
to the left position.<br />
If the batteries have enough capacity, the ready indicator (1.16) will light up<br />
after about 5 seconds. At the same time – if the function is activated – an acoustic<br />
signal will sound (see “Beep function”, p. 64). The proper functioning of the<br />
flash unit can then be checked by activating this button, which functions simultaneously<br />
as flash trigger. The following charging processes should be completed<br />
after about 0.5-3.5 s.<br />
If the flash-ready indicator only lights up much later or does not light up at all,<br />
the batteries must be replaced with new or recharged ones. If there is then still<br />
no reaction, this may be because the contacts of the power sources or those in<br />
the flash unit are soiled. In this case, they must be wiped clean with a clean,<br />
dry and lint-free cloth.<br />
Notes:<br />
• In the case of the LEICA R 8 / R 9 and the LEICA M 6 TTL-, M 7- and M 8 models,<br />
a flash-ready indication is simultaneously shown in their viewfinder displays<br />
too.<br />
• If there is no flash-ready indication (yet), the <strong>Leica</strong> models with TTL control<br />
will automatically switch to using the operating mode they are set to without<br />
an attached flash unit.<br />
• If the <strong>SF</strong> <strong>58</strong> is not attached to the LEICA R 8 / R 9, the LEICA M 6 TTL-, M 7 or M 8<br />
models, or if the cameras mentioned are not switched on and powered up,<br />
the ready indicator of the flash unit (1.16) will only light up if the flash unit is<br />
set to A<br />
or M .<br />
• If the flash unit is not required for a lengthy period, it should always be switched<br />
off by the main switch and the power sources (batteries/rechargeable batteries)<br />
should be removed from the flash unit.
