  If you are experiencing a weak intensity level with your Omron Medical Equipment, ensure you are using both pads, and that you've removed the transparent film from the pad's adhesive surface. Also, make sure the pads aren't stacked or overlapping, and that the cord is properly connected to the unit. Check if the intensity setting is low and increase it by pressing the up button. If the gel is damaged or the batteries are weak, replace the pad or batteries, respectively. Finally, ensure the intensity is not set to '1', and increase it if necessary.

What to do if the pad gel does not stick to skin for Omron Pocket Pain Pro PM400?

  If the pad gel of your Omron Medical Equipment doesn't stick to the skin, start by peeling off the transparent film from the pad's adhesive surface. Ensure that neither the pad nor your skin is excessively wet; dry them if necessary. If the pad gel is damaged, replace it. If there's too much hair, shave the area. Clean the pad's adhesive surface gently under slow running cold water for about 3 seconds if it's dirty or dry. If perspiring, dry the pad placement area. For pads washed too long or frequently, leave them in the freezer overnight. Replace pads stored under high temperature, high humidity, or direct sunshine.
