Function Procedure
Trend-Like function
limits
Make sure that the Trend-Like function handles are accessible
on both sides of the bed, and check for proper handle functions as
follows:
• Push down on the Trend-Like function handle. The head end
lowers from the level position to 8°, relative to the foot end.
• Pull up on the Trend-Like function handle. The head rises from the
Trend-Like position to the level position.
• Repeat the steps using the Trend-Like function handle on the other
side of the bed.
Hilow limits Operate the hilow section to the full upper and lower limits. See
“Checking the Hilow Limit Switch” on page 4-11. Check that the
position sensors function properly.
Head limits Operate the head section to the full upper and lower limits. Check that
the position sensors function properly.
Foot limits Operate the foot section to the full upper and lower limits. See
“Checking the Foot Limit Switch” on page 4-21. Check that the
position sensors function properly.
LED indicators Check all LED indicators on the caregiver control panel for proper
operation.
Night light Check the night light for proper functioning. The sensor for this light
is very sensitive to ambient light and does not turn on the light unless
placed in complete darkness. To test, cover the sensor completely
with a folded dark cloth.
Pendant control Check the pendant control for proper operation. Visually inspect the
cord to ensure it has no cuts, nicks, or breaks. Replace if necessary.
Pivot points Inspect the shoulder bolts through the pivot blocks on the frame (see
figure 6-1 on page 6-7). Apply Loctite® adhesive, and tighten if
necessary.
Inspect pivot points for wear, and lubricate if noisy.
