1. Introduction

The Mattress consists of a foam head cell and series of 14 transverse air cells, each containing a unique

foam profiled insert, which are in turn held within a foam U Core, all protected by a vapour permeable

waterproof cover. The single head end cell and the formers consist of foam only. The transverse cells are

arranged into alternate pairs of A and B cells which are filled and emptied in sequence.

In Static Mode, the mattress attains the pressure reducing properties of the Dyna-Form Mercury

static foam mattress (details available on request), whilst in Alternating Mode the mattress is able to

offer similar properties to a pressure relieving dynamic system.

The digital Control Unit controls a Control Unit that allows air to flow into, or out of the air cells as

required according to the operating mode selected. It also maintains the air pressure within the

mattress at the required level and controls the action of the audible/visual Audible Warning system

in the event of mains supply failure or over or under inflation pressure. A CPR Valve located at the

Control Unit end of the umbilical hose permits the rapid deflation of the Mattress in an emergency.

2. Quick Reference Guide

(Frequently used functions)

This is a quick reference guide for the Dyna-Form Mercury Advance System

Product Code MAT1210001

Power Switch Audible Warning Reset

The power switch simply switches the mains power to the Control Unit on and off.

When the Control Unit detects an Audible Warning condition, this can be silenced (see page 5)

and re-set by switching the Control Unit off and then back on again.

CPR Valve

Please ensure that the CPR connector is always placed fully home, prior to inflating the mattress.

NB: The mattress will NOT inflate properly should this not be the case.

The CPR connector is only to be used in the event of a clinical emergency for priority use.

However, disconnecting this function will cleverly deflate air rapidly from the mattress in

readiness for transport / static mode.

LED Mode Settings

This symbol when illuminated (The green indicator light) is used to indicate that the equipment is

on or ready for use.

When a patient requires a true dynamic function or indeed more pressure in the cells, as they

may be uncomfortable or feel as though the support surface is too soft or unstable, then please

select a "High" setting (pressure 26mmHg). This must only be used by a trained clinician as often

too high pressures can further agitate certain patient conditions.

When a patient requires less pressure in the cells, as they may be uncomfortable or indeed hyper

sensitive to cell movement or indeed if the patient is still reddening further, then please select a

"Low" setting (pressure 18mmHg). This must only be used by a trained clinician.

This function is used to silence the Audible Warning. The LED will remain lit if the Audible

Warning has been silenced previously, however a fault is still detected. Refer to the power switch

in order to re-set fully. If the Audible Warning continues to sound repeatedly, along with an

illuminated light, then an engineer must be called.

This symbol indicates an "Audible Warning Failure".

Please see troubleshooting guide below for how to re-set.

This symbol when illuminated indicates a Service is required.

DHG recommends an annual service. The service light will illuminate every 8760 hours of

operation (one continuous year running).

Note: Please ensure (when available) that all securing straps on the base of the mattress are secured onto

the MOVING PARTS of the bed frame.

For shut down procedure, see 4.2 Control Unit section.
