00:00What is a pager and how does it work?

00:02Let's take a look at how pager works.

00:05At its core, the battery powers the entire device.

00:08This is the speaker, which emits audio alerts to notify the user of incoming messages.

00:14The motor adds a physical vibration alert, making the pager effective in silent mode.

00:20The radio antenna coil receives wireless signals like VHF,

00:25and the microprocessor converts these signals into readable messages.

00:29In short, these are often low-tech and difficult to track.

00:33Inside a typical pager, you'll notice these components working together,

00:37particularly the batteries which power the device.

00:41Now, let's consider a hypothetical scenario.

00:44Imagine you're looking at two identical batteries inside the pager.

00:48Although this is speculative, if it were part of a spy agency,

00:53we might consider disguising one of the two identical batteries for a different purpose.

00:58One battery would provide the necessary power for the device,

01:01while the other could potentially serve as an explosive cleverly concealed within the pager.

01:08To expand on this theory, an alkaline AA battery weighs approximately 23 grams.

01:14Interestingly, reports in the news have mentioned that an explosive weighing about 20 grams was detonated.

01:21This similarity in weight lends some plausibility to the idea

01:25that a battery could be used as a disguised explosive device.

01:30Lebanon ordered around 5,000 pagers from Taiwan,

01:34a country known for producing about 90% of the world's most advanced semiconductors.

01:40These pagers were destined for Lebanon.

01:43However, what makes this story particularly intriguing

01:47is what allegedly happened during the shipment process.

01:50At some point along the way, a spy agency is believed to have intercepted the shipment

01:55and tampered with the pagers.

01:57They discreetly altered the internal components,

02:00replacing one of the two identical batteries with a hidden explosive device.

02:05This modification was done so subtly that it went unnoticed.

02:09Once the changes were made, the altered pagers were quietly sent back to Lebanon

02:14as if nothing had happened.
