CHAPTER 1: INTRODUCTION  
The N500 series Electronic Postal Scale is a 2kg capacity decision  
making scale which uses computer technology to give you an accurate,  
automatic display of weight, postal rate and charges. Place the mail on  
the scale and select the appropriate category and any fees required; the  
scale will display the correct postal charges.  
ABOUT YOUR  
SCALE  
The postage rate information is all contained within a small electronic  
‘chip’ called a PROM. When the postage rates change, you can easily  
remove the old PROM and fit a new one to instantly update your scale.  
If the scale is linked to a Pitney Bowes electronic postage meter, it can  
automatically set the postage value and control the accounts set up on  
the postage meter.  
If the scale is linked to a Pitney Bowes Electronic Postage Meter with a  
Mailing Base capable of tape dispensing, the scale will also enable a tape  
to be produced automatically.  
The scale enters sleep mode if it remains inactive at zero weight for  
more than three minutes. During sleep mode, the display is  
extinguished.  
Sleep Mode  
Never attempt to remove covers from your scale. No user serviceable  
parts are contained within the unit, servicing should be referred to  
qualified personnel.  
SAFETY  
PRECAUTIONS  
The scale platform may be removed to gain access to the Postage Rate  
PROM (see page 26). Always ensure power is turned OFF at the mains  
socket outlet before removing the platform.  
The N500 is supplied with a power supply suitable for use on standard  
UK 13A mains sockets. Only the power supply provided with the scale  
should be used.  
Mains electrical  
connection  
Note:  
The socket outlet should be near to the equipment  
and should be easily accessible.

CHAPTER 2: USING YOUR SCALE  
The following assumes you or a Pitney Bowes engineer have completed  
USING THE SCALE  
the installation instructions included with your scale. If not, please do  
so now. Ensure that before you start using your scale, you check that the  
scale has been levelled correctly (see page 26).  
Where possible, sort items of mail into batches of like categories, i.e. 1st  
Class or 2nd Class etc. This will minimise category changing.  
Your scale should be turned ON and ready for use. The display will  
show 0g (provided the weighing platform is empty) and the Select  
Category prompt.  
During operation, if the scale is at zero weight and not used for 3  
minutes, it will enter Sleep Mode. During Sleep Mode the display is  
extinguished.  
Sleep Mode  
When a weight is placed on the platform or any key is pressed, the  
display will relight with all the previous selections showing.  
If your scale is linked to a postage meter which has internal accounting,  
you must select a valid account before you start processing mail on the  
scale. This operation can be done from the scale keyboard. Dependant  
upon whether you have the Datalink option fitted to your postage  
meter, one of the following two methods will allow you to select the  
account. First, press the Account key…  
Postage Meter

the screen, press the menu selection key alongside the account to select.  
or…  
If the display prompts you to enter an account number, key in a valid

without adding fees, or you can add fees as required.  
Choosing Fees  
To add a fee, press the Menu Selection key alongside the fee you want.  
If the fee selected is value dependent (varies with the value of the item  
to be mailed), the scale will ask you to enter the value of the item. Key  
in the value on the numeric keys followed by the Enter key. Values are  
in pounds unless you enter the decimal point i.e.  
key in… 500 for £500  
key in… 5.01 for £5.01  
The display will show a tick alongside the fee selected and the value will  
be added to the postage amount in the display.  
The display will show additional fees which are still valid. If desired,  
you may continue to add these extra fees.  
You can de-select any fee you have added by pressing the Menu  
Selection key alongside the fee. The tick will be extinguished and the  
fee value will be removed from the postage value on the display.

Category and return to ready mode. Then manually add the value as  
described above.  
If your N500 is linked to a Pitney Bowes electronic  
postage meter, you can set the meter to the postage  
amount displayed by pressing the Meter Set key at the  
bottom of the keyboard. The meter ‘ready’ symbol ( )  
will appear on the display each side of the value.

CHAPTER 2: USING YOUR SCALE  
The weight hold feature is useful when weighing large envelopes that  
USING THE  
WEIGHT HOLD  
FEATURE  
block the display. This feature retains the weight reading for a brief  
time after you remove an item from the scale. It allows you to continue  
selecting categories and fees even though the item is no longer on the  
scale. Pressing any key other than zero (for example, to select a category  
of fee) extends the weight hold time for that transaction.  
To use the weight hold feature for one transaction:  
1. Press the Weight Hold key and place a mailpiece on the scale.  
Result: "Hold" appears on the display (only if no weight is on the  
scale).  
2. Remove the mailpiece from the scale and note that the weight  
reading remains.  
3. Select a category and apply fees if desired.  
To exit manual weight hold, wait a few seconds until the hold feature  
times out or press Zero.  
Note: The weight hold feature can be configured to automatically  
operate for all mailpieces placed on to the platform if required. (See  
page 19 - Changing Setup Options).

and the item you are weighing requires £110 of postage:  
1. Press the Meter Set or Tape key. The  
postage amount and Currency  
Breakdown prompt displays to  
indicate the total exceeds the meter's  
printing capacity.  
2. Press the Meter Set or Tape key again. The meter sets to £99.99  
and generates a tape (if tape was selected) for that amount. The  
remaining amount is displayed on the scale.  
3. Press the Meter Set or Tape key again. The meter sets to the  
remaining amount and generates a tape (if tape was selected) for  
that amount. The scale display returns to the original total postage  
amount.  
4. Remove the item from the scale and press C/CE twice to return to  
ready mode.  
To cancel the currency breakdown function, press C/CE any time

CHAPTER 4: MAINTAINING YOUR SCALE  
Your scale requires very little maintenance. Simply keep it clean by  
wiping it with a soft dry cloth. Do not use harsh chemical cleaners on  
your scale.  
CLEANING  
LEVELLING  
The scale must have a firm base  
and be level to give its best  
performance.  
To level the scale, adjust the four  
feet until the bubble in the  
levelling device on top of the  
platform is centralised.  
Turn the feet clockwise to raise them or anticlockwise to lower them.  
This section describes how to update the postage rates  
contained within your scale by removing the old  
PROM and fitting a new one.  
POSTAGE RATE  
(PROM) CHANGE  
Service Maintenance Contracts in the UK may  
include automatic supply of a new PROM at a  
Rate PROM  
postage rate change. If not, or if you do not have a  
Maintenance Contract, you will need to order a new PROM from  
Pitney Bowes at each rate change.  
The PROM is located in a slot  
under the weighing platform.  
The PROM’s label gives details of  
the PROM part number, country  
and revision date.
