    Gralab 900 manual

    Does anyone here have an owners manual for the Gralab 900 timer that I can get a copy of? Or know of a working link to one online?

    Baring either of the above, how about telling me what sequence of buttons to push to program in a 3-step sequence? Say 1min, then 2 min, then 3 min?

    I don't know if I have an electronic manual. From memory, this is how you would program a 3 step sequence when each step starts as soon as the preceding step ends:

    Press clear
    Press "3"
    Press "minutes"
    Press "25"
    Press "seconds"

    That sets the time. Then start at the top row of the various functions:

    For "Memory Location.."
    Press "Forward"
    For "Function"
    Press "Autostart"
    For "Audio"
    Press "Warning" (That turns on a metronome for the last 10 sec.)
    For "Display"
    Press "Medium" (or your preference)
    For "Count"
    Press "Down" (or "Up")

    Now set the memory:

    Press "Memory Loc"
    Press "0" (zero is the first step rather than 1)

    That sets the first step into memory. For subsequent steps, repeat the above process except that after you press "Memory Loc" you will press 1, 2, 3... to set the second, third, and fourth steps as needed up to a maximum of 9 steps.

    It is easier and quicker to do than it sounds.

    Once you are done programming the sequence, do this to get started:

    Press "Clear"
    Press "Recall"
    Press "Memory Loc"
    Press "0" (zero on the keypad)

    Now you are set for the first step of 3 min:25 sec as programmed above.

    Press the foot switch or the Start button to begin. Press either in midstream to pause. If you turn the power off, the sequence disappears because it is not held in internal memory. If you want to retain the same sequence between sessions, it is easier to press "Display" "Off" when you leave and "Display" "On" when you return.

    I just made you a copy of the printed manual. PM me with your address and I will send it Monday.

    Bump ...

    I just bought one of these 900s! However, no manual, so I will appeal to the brotherhood if Mr Harter or anyone else can supply me with one.

    Thanks!

    WOW! I am looking for a PDF as well. Just picked one up for a friend's daughter. She has just fallen in love with film and I gave her a complete darkroom but did not have a decent timer for her. Would love a PDF. Thanks in advance!

    I guess it is my turn to return the favor. PM an email address and I'll pass this along.
