special sealed NiCd battery for top

' recycling is under 2 seconds with
this accessory. Transistor Pack E
is made exclusively for the 430 EZ.
To maintain TTL flash operation for
off-camera or multiple flash
photography, the EOS-l is
compatible with Canon's TTL Hot
Shoe Adapter 2, TTL Distributor,
the Off Camera Shoe Adapters, and
Connecting Cords 60 (2 ft.) and 300
(9.8 ft.).
EOS-l also features a built-in
threaded PC socket for non-
dedicated flash. Both the hot shoe
and the PC socket can be used
simultaneously for multiple flash
photography.
Although 1/250 sync is guaranteed
with Canon Speedlites, we recommend
conducting a film test to check
maximum sync speed with studio
strobes and wireless remotes. The
1/3 step shutter speeds of the EOS-
1
are particularly useful for this
purpose, providing settings of
1/200 and 1/160 for use as needed.
9. COMMAND BACK El PROVIDES DATA
IMPRINT AND INTERVALOMETER
FUNCTIONS.
This accessory replaces the
standard EOS-1 back for data
imprint and/or timer controlled
photography. The photographer can
select any of several different
imprint modes as follows:

The intervalometer supplies 3
distinct sequence-control functions
plus a fourth control which defines
the total number of exposures in
the cycle.
The self timer sets the delay from
the beginning of the sequence until
the first exposure. The interval
setting then regulates the length
of time between exposures. The long
release timer actually serves two
purposes: it can either determine
the duration of bulb exposures when
the camera is set to bulb; or
alternatively it can be used to
vary the number of AE or manual
exposures that are taken at the
user-specified interval. All of
these settings can be made up to 23
hours, 59 minutes, and 59 seconds
in 1 second increments.
Data imprinting can be freely
combined with timer control.
Additionally, the Command Back E1
has the capability of controlling a
Speedlite during time-lapse
photography, activating the flash
60 seconds before each exposure.
The Speedlite's Save Energy (SE)
function then automatically turns
the unit off.
