\rtlch\fcs1 \af0 \ltrch\fcs0 \insrsid6977686  for more info.\line Requires Oolite 1.75.2\line \line Overview: \line \line Upgrade to the IFF (lollipop) scanner system which highlights ships with an offender or fugitive legal status with custom \lquote 
lollipop\rquote  colours to allow rapid visual identification of criminals via the scanner.\line \line Description:\line \line In a bid to raise fun
ds to replace their ageing Viper fleet, and in recognition of the lack of control they are exhibiting over many of the space lanes, Galcop have licensed a civilian version of the IFF scanner unit used in Police ships to quickly identify criminals in fligh
t. \line \line 
Welcomed by both Bounty Hunters wanting that extra few seconds advantage in identifying targets and nervous traders wanting an extra few seconds to avoid potentially hostile pirates the unit is available from Tech Level 12 or above planets for the prin
cely sum of 2500 credits. It can also be resold for 60% refund of normal sale price at Tech level 12 or above. There is a 10 credit admin fee to sell the equipment.\line \line 
The unit complements the Bounty Scanner equipment and has also been designed to work well with the Target Autolock Plus equipment. It is particularly useful when players run into an ongoing furball to quickly work out who the \lquote bad\rquote  guys are.
\line \line Once installed ships (excluding Thargoids) with an offender status are displayed on the scanner as flashing yellow/orange \lquote lollipops\rquote , whilst fugitives are displayed as flashing }{\rtlch\fcs1 \af0 \ltrch\fcs0 \insrsid4136354 o
ange}{\rtlch\fcs1 \af0 \ltrch\fcs0 \insrsid6977686 /magenta \lquote lollipops\rquote , instead of the default yellow. If targeting and hostile to the player both offender and fugitive ships turn deep red on the scanner.\line \line Change Log:\line \line 
Version 1: 19/6/11 \endash  Initial release.\line \line Version 1.1: 21/6/11 \endash  Bug fix to the timer mechanism that updates the scanner to avoid log warning messages.\line \line 
Version 1.2: 25/6/11 - Fixed a 'silent' bug in timer mechanism. Added code to stop Timer on ship death.}{\rtlch\fcs1 \af0 \ltrch\fcs0 \insrsid16544959 
\par }{\rtlch\fcs1 \af0 \ltrch\fcs0 \insrsid6977686 
\par Version 1.3: 24/9/11 \endash  Added code to script so that scanner colours are always reset properly if the Police Scanner is damaged in combat.
\par }{\rtlch\fcs1 \af0 \ltrch\fcs0 \insrsid4136354 
\par Version 1.3.1 18/12/11 \endash  Minor update. Code is now compliant with JavaScript strict mode. Fugitives now have orange/magenta lollipop colours to differentiate them slightly from hired guns.}{\rtlch\fcs1 \af0\afs20 \ltrch\fcs0
