Unpacking and Storage of Your Equipment

Unpacking

It is extremely important that you check the contents of your equipment immediately upon receipt to

ensure that your order is complete and that it has arrived safely. Please refer to the packing list to show

all items that are included with your order. DO NOT DISCARD ANY OF THE PACKAGING MATERIAL

UNTIL ALL OF THE ITEMS LISTED ARE ACCOUNTED FOR. WE RECOMMEND THAT YOU RETAIN

THE ORIGINAL PACKING FOR FUTURE USE. If you suspect that any of the items listed on the packing

list are not included or damaged, you must contact PP Systems or your authorized distributor

immediately.

EGM-5 Operation Manual V. 1.04 9 [email protected]

Powering up the EGM-5 for the First Time

When you receive your new EGM-5 from PP Systems you will need to first connect it up to the external

power supply/charger prior to powering up the instrument. To avoid accidental power up during shipment

we put the instrument into “Ship Mode” (see Ship Mode on page 53). Therefore, when you are ready to

begin:

1. Locate the power supply/charger and power cord inside the packing box.

2. Connect the AC power cord to the mains and the barrel connector into the EXT Power socket on

the back of the EGM-5.

3. Press the ON/OFF switch to power up the instrument. The power switch should now have an

illuminating blue ring indicating power is on.

4. Allow 10-15 minutes to achieve warm-up.

You are ready to go!

Data Storage

For convenience and ease it is very important to note that all EGM-5 system data is recorded and saved

directly to a USB flash drive (i.e. memory stick or thumb drive). A USB flash drive is included in the spares

kit (Part No. 43034-1) with every new system.

THEREFORE IT IS IMPERATIVE THAT YOU HAVE A USB FLASH DRIVE WITH YOU AT ALL TIMES

IF YOU WANT TO RECORD DATA WITH YOUR EGM-5. OTHERWISE DATA WILL HAVE TO BE

RECORDED MANUALLY.
