ASAHI PENTAXMOTORDRIVE MX
Motor Drive MX is designedexclusivelyfor use with the Asahi
Pentax MX camera. The unit can be used witlt all shutter speeds,
other than Bulb (1 11000- 1 sec.),and the motorization rate has
a steplesslyvariable range of 0.5 - 5 fps with all shutter speeds
shorter than 1/3O second (1 /1000 - 1/60 sec.). Moreover,three
power sourcesare available:penlight batteriesvia Battery Grip M,
rechargeablenickel cadmium batteriesvia Ni-Cd Battery Pack M,
the normal AC household power supply via Power Pack M.
Motorization up to 5 fps is still possiblewith the Pentax MX when
using Dial Data MX or the Bulk Film MagazineBack.
Battery Grip M, Ni-Cd Battery Pack M, and Power Pack M can
also be used with the Pentax K2 DMD Motor Drive MD unit.
For detailed instructions on the Pentax MX, refer to the instruction
manual suppliedwith the camera.Since this manual coversnot only
Motor Drive M X, but its related accessories,no additional instructions
are supplied with optional accessories.Care should therefore be
taken not to lose this manual.
