CALIBRATION METHOD TO SET TRAVEL
LIMITS
The jack is calibrated at the factory and is ready for
use when taken out of the box. IF THE JACK HAS
BEEN MANUALLY OPERATED, SERVICED OR IF THE
JACK IS SUSPECTED TO BE OUT OF CALIBRATION FOR
WHATEVER REASON, THEN USER SHOULD RECALI‐
BRATE THE TRAVEL LIMITS. To calibrate the travel
limits of the jack, follow these steps:
1. Press and hold Extend/Retract button for three
(3) seconds and GREEN light will flash three (3)
times indicating both buttons are pushed.
2. After three (3) seconds the WHITE light will flash
indicating the jack is in calibration mode. Press
Extend or Retract button so that the end of the
outer tube is located on the top edge of the cali‐
bration hole (see parts list view).
3. Press and hold ON/OFF button until WHITE light
goes off indicating that the jack is now calibrated.
After the white light goes off, the jack will imme‐
diately move (up or down about ᶟ⁄₈") to set the
location sensor. The calibration hole should not
be visible after the location sensor has set.
4. Jack is now ready to use by pushing Extend or
Retract buttons.

PHOENIX 4000 ELECTRIC TONGUE JACK
TWO MEMORY BUTTONS
(Mem 1 & Mem 2)
These can be used to remember certain height loca‐
tions such as hooking and unhooking from tow vehi‐
cle and a second memory option to remember a sec‐
ond height location such as height required to attach
chains for a weight distributing hitch.
While unhooking from the tow vehicle, Extend/
Retract the jack to the desired location that allows
the coupler to clear the hitch ball and unhook the
trailer from the tow vehicle. This is the position that
jack will return to while hooking back up to the tow
vehicle by following these steps:
1. Push and hold the Mem 1 Memory Button for
three (3) seconds and the GREEN light flashes
three (3) times to set the memorized position of
the jack at the desired height.
2. Once the Memory position has been set, pushing
the Mem 1 button will take the jack to the
memorized location.
3. Once the jack is traveling to the memory location
and user wants to stop the jack for whatever rea‐
son, press the memory button again and the jack
will stop. To resume the memory function, press
the memory button and the jack will proceed to
the memory location.
4. Otherwise, use the Extend and Retract buttons to
operate the jack. The memory button should
only be used to set the memory location and to
travel to the memory location.
5.
To set the second memory position follow steps
1 through 4 using the Mem 2 button instead of
the Mem 1 button.
